So, keep practicing! --- ## Specific to the Teachers/Coaches This book is based on Steven's CS3232 - 'Competitive Programming' course in the School of Computing, National University of Singapore. It is contributed to its teaching teams using the following lesson plan (see Table 2). The PDF slides (only the public versions) can be found in the companion website of this book. This lesson plan contains the various exercises in this book as seen in Appendix A. Fellow teachers/coaches are free to modify the lesson plan to suit your students' needs. | Wk | Topic | In This Book | |----|---------------------------------------------|-----------------------------------| | 01 | Introduction | Chapter 1 | | 02 | Data Structures & Libraries | Chapter 2 | | 03 | Combinatorial Search, Divide & Conquer, Greedy | Section 3.2.4 | | 04 | Dynamic Programming (1: Basic Ideas) | Section 3.2.3 | | 05 | Graphs (1: DFS/BFS) | Chapter 4 | | 06 | Graphs (2: Shortest Paths, Dijkstra) | Section 4.4.5 - 4.17.2 | | 07 | Mid semester break contact | | | 08 | Dynamic Programming (2: More Techniques) | Section 6.3.4 | | 09 | Graphs (3: Max Flow; Bipartite Graph) | Section 6.4.3, 4.7.4 | | 10 | Mathematics (Overview) | Chapter 5 | | 11 | String Processing (Basics, Suffix Array) | Chapter 6 | | 12 | Computational Geometry (Libraries) | Chapter 7 | | | Final exam content | All, including Chapter 8 | **Table 2:** Lesson Plan --- ## To All Readers Due to the diversity of this content, this book is not meant to be read once, but several times. There are exercises that can be skipped at first if the content is too intense at that point of time, but the reader is encouraged to come back and revisit numerous sections when the concepts are more settled. While we strive to present the concepts in this book in a clear, intuitive manner, there are twists we cannot always predict. Make sure to attempt them alone. We believe that this book should lead the aspiring student towards the logical standards as IPC will lead them to the appropriate programming problems. This book is intended for proficient personnel in the field before facing more challenges after mastering this book. But before you assume anything, please check this book's table of contents to see what we mean by "basic". ``` #################### File:

sequence of chapters for a short introductory course. --- Depending on the length of the instruction period, the background of students, and your interests, you may select subsets of chapters to teach in various sequential orderings. For example, if you would like to give only a short introduction to students on data mining, you may follow the suggested sequence in Figure P.1. Notice that depending on the need, you can also omit some sections or subsections in a chapter if desired. Depending on the length of the course and its technical scope, you may choose to selectively add more chapters to this preliminary sequence. For example, instructors who are more interested in advanced classification methods may first add "Chapter 9. Classification: Advanced Methods"; those more interested in pattern mining may choose to include "Chapter 7. Advanced Pattern Mining"; whereas those interested in OLAP and data cube technology may like to add "Chapter 4. Data Warehousing and Online Analytical Processing" and "Chapter 5. Data Cube Technology." Alternatively, you may choose to teach the whole book in a two-course sequence that covers all of the chapters in the book, plus, where time permits, some advanced topics such as graph and network mining. Material for such advanced topics may be selected from the companion chapters available from the book's web site, accompanied with a set of selected research papers. Individual chapters in this book can also be used for tutorials or for special topics in related courses, such as machine learning, pattern recognition, data warehousing, and intelligent data analysis. Each chapter ends with a set of exercises, suitable as assigned homework. The exercises after each chapter question that test basic mastery of the material covered, longer questions that require analytical thinking, or implementing projects. Some exercises can also be used as research discussion topics. The bibliographic notes at the end of each chapter can be used in the research literature related to the concepts and methods presented, in-depth treatment of related topics, and possible extensions. --- ## To the Student We hope that this textbook will spark your interest in the ever fast-evolving field of data mining. We have attempted to present the material in a clear manner, with careful explanation of the topics covered. Each chapter ends with a summary describing the main points. We have included many figures and illustrations throughout the text to make the book more enjoyable and reader-friendly. Although this book was designed as a textbook, we have tried to organize it so that it will also be useful to you as a reference. #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 28 Context: # Preface ## Figure P.1 A suggested sequence of chapters for a short introductory course.

Introduction to Data Mining Data mining involves discovering patterns in large data sets. It utilizes techniques from machine learning, statistics, and database systems. ### 2. Data Preprocessing Data preprocessing is vital for effective data mining. Key steps include: - **Data Cleaning**: Removing noise and inconsistencies. - **Data Integration**: Combining data from different sources. - **Data Transformation**: Converting data into suitable formats. ### 3. Data Warehousing and OLAP Data warehouses store integrated data from multiple sources to enable analytical querying. OLAP allows for multi-dimensional data analysis. ### 4. Data Mining Techniques #### A. Classification Classification is used to categorize data points into predefined classes. Common algorithms include decision trees, random forests, and support vector machines. #### B. Clustering Clustering involves grouping data points based on similarity. Key algorithms include k-means and hierarchical clustering. #### C. Association Rule Learning This technique identifies interesting relationships between variables in large databases (e.g., market basket analysis). ### 5. Evaluation of Data Mining Evaluating the effectiveness of data mining can be done through: - **Accuracy metrics**: Precision, recall, and F1 score. - **Visualizations**: ROC curves and confusion matrices. --- ## References - Han, J., Kamber, M., & Pei, J.

(b) Compute the Manhattan distance between the two objects. (c) Compute the Minkowski distance between the two objects, using \( q = 3 \). (d) Compute the supremum distance between the two objects. ## 2.7 The median is one of the most important holistic measures in data analysis. Propose several methods for median approximation. Analyze their respective complexity under different parameter settings and decide to what extent the real value can be approximated. Moreover, suggest a heuristic strategy to balance between accuracy and complexity and then apply it to all methods you have given. ## 2.8 It is important to define or select similarity measures in data analysis. However, there is no commonly accepted subjective similarity measure. Results can vary depending on the similarity measures used. Nonetheless, seemingly different similarity measures may be equivalent after some transformation. Suppose we have the following 2-D data set: | A1 | A2 | |-----|-----| | x1 | 1.5 | 1.7 | | x2 | 2.2 | 1.9 | | x3 | 1.6 | 1.8 | | x4 | 1.2 | 1.5 | | x5 | 1.5 | 1.0 | (a) Consider the data as 2-D data points. Given a new data point, \( x = (1.4, 1.6) \) as a query, rank the database points based on similarity with the query using Euclidean distance, Manhattan distance, supremum distance, and cosine similarity. (b) Normalize the data set to make the norm of each data point equal to 1. Use Euclidean distance on the transformed data to rank the data points. ## 2.7 Bibliographic Notes Methods for descriptive data summarization have been studied in the statistics literature long before the onset of computers. Good summaries of statistical descriptive data mining methods include Freedman, Pisani, and Purves [FP97] and Devore [Dev95]. ``` #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 1 Context: # Data Mining: Concepts and Techniques **Third Edition** **Authors:** Jiawei Han, Micheline Kamber, Jian Pei **Publisher:** Morgan Kaufmann ## Table of Contents 1. **Introduction** 2. **Data Mining Concepts** 3. **Data Preprocessing** 4. **Data Warehousing** 5. **Data Mining Techniques** 6. **Mining Frequent Patterns** 7. **Classification** 8. **Clustering** 9. **Evaluation of Data Mining Models** 10. **Applications of Data Mining** ## Chapter Overview ### Chapter 1: Introduction - Definition and scope of data mining. - Importance in various fields. ### Chapter 2: Data Mining Concepts - Overview of data mining process. - Key techniques and terminology. ### Chapter 3: Data Preprocessing - Data cleaning and transformation. - Handling missing values. ### Chapter 4: Data Warehousing - Techniques to store and manage data. - Summary of data warehousing design. ### Chapter 5: Data Mining Techniques - Overview of different mining techniques. - Examples and use cases. ### Chapter 6: Mining Frequent Patterns - Methods for pattern discovery. - Applications in market basket analysis. ### Chapter 7: Classification - Overview of classification techniques. - Decision trees and other methods. ### Chapter 8: Clustering - Introduction to clustering algorithms. - Applications and evaluation metrics. ### Chapter 9: Evaluation of Data Mining Models - Techniques for model assessment. - Cross-validation and performance metrics. ### Chapter 10: Applications of Data Mining - Case studies in various domains. - Future trends in data mining. ## References - A comprehensive list of references for further reading. ## Index - An alphabetical index for easy navigation of topics covered in the book. --- #################### File: Analytic%20Geometry%20%281922%29%20-%20Lewis%20Parker%20Siceloff%2C%20George%20Wentworth%2C%20David%20Eugene%20Smith%20%28PDF%29.pdf Page: 295 Context: ``` # INDEX | Subject | PAGE | |--------------------------|-------| | Alecsis | 5 | | Analytic geometry | 2.97 | | Angle between circles | 6.1 | | Area | 160, 240, 249 | | Asymptote | 47, 170, 181 | | Asymptotic cone | 271 | | Auxiliary circle | 101 | | Axis | 17, 117, 142, 160, 188, 209, 237 | | Center | 142, 180, 184 | | Central conic | 105 | | Closed | 112, 113, 128 | | Conic | 112 | | Conic section | 215 | | Conical | 114 | | Conjugate axis | 190 | | Hyperbola | 172 | | Cylinder | 74, 94, 204, 219 | | Coordinates | 1.0, 1.01, 0.99, 237 | | Cylindrical | 0.1 | | Degenerate cone | 199, 302 | | Diameter | 183, 167, 184 | ## Direction cosine - PAGE: 340, 248 ## Direction - PAGE: 114, 141, 169 ## Discriminant - PAGE: 113, 130, 179 ## Distance - PAGE: 14, 16, 175, 249, 262 ## Division of lines - PAGE: 238, 242 ## Duplication of the cube - PAGE: 219 ### Eccentric angle - PAGE: 115, 180 ### Eccentricity - PAGE: 115, 130, 178 ### Equation of a circle - PAGE: 8, 36, 191 ### Equation of an ellipse - PAGE: 142, 180, 186 ### Equation of a hyperbola - PAGE: 186, 189 ### Equation of a tangent - PAGE: 96, 142, 150, 179 ### Equation of second degree - PAGE: 111, 190, 268 ### Exponential curve - PAGE: 242, 244 ### Focal width - PAGE: 117, 142, 170 ### Focus - PAGE: 116, 141, 146 ### Function - PAGE: 64 ## Geometric locus - magnitude: PAGE: 8, 13, 83, 212 ### Graph - PAGE: 15 ``` #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 245 Context: # Bibliography 1.

(a) Do you know how to store a string in your favorite programming language? (b) How to read a given text input line by line? (c) How to concatenate (combine) two strings into a larger one? (d) How to check if a string starts with `......` to stop reading input? I love CS2333 Competitive Programming. I also love Algorithms! > **Note:** You must stop after reading this line as it starts with 7 dots. After the first input block, there will be looooooooccccccooooonnng line... 2. Suppose we have the input string T. We want to check if another string P can be found in T. Report all the indexes where P appears in T or report -1 if P cannot be found in T. For example, if T = "I love CS2333 Competitive Programming", and P = "love", the output should only be the index(es) where P occurs. If P is not considered default, then the character `1` and index `2` is part of the output. If P = "box", then the output is [-1]. (a) How to find the first occurrence of a substring in a string? (b) Do we need to implement a string matching algorithm (like Knuth-Morris-Pratt (KMP) algorithm discussed in Section 6.4), or can we use just Library functions? 3. Suppose we want to do some simple analysis of the characters in T and also to transform each character into 1 into lowercase. The required analysis asks: How many digits, vowels, and arrays of characters (lower/upper) wherever the index starts from 0 to `n` (where n is the length of the array). (a) Next, we want to break this into strings into tokens (substrings) and into that form an array of individual tokens. For this task, the boundaries of these tokens are spaces and punctuations (since tokens must work). For example, the string `I love CS2333, 'i', 'love', 'programming'`. (b) How to store an array of strings? 4. Next, we want to start this over and string lexicographically. (a) How to read a string over the internet if we do not know its length in advance? (b) The given list has one more item like the one used in our common dictionary. The length of this list has been constrained. Count how many characters are there in the last item? (c) Which data structure best supports this word frequency counting problem? (d) The string contains a common utility keyword: 'algorithm'. ``` #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 248 Context: # INDEX - Factorial, 316 - Fenwick Tree, 35 - Fuzzy Logic, M. 32 - Fibonacci Numbers, 129 - Flood Fill, 71 - Floyd Warshall's, 96 - Floyd, Robert W., 95 - Food P.

Compute the **Euclidean distance** between the two objects. 2. Compute the **Manhattan distance** between the two objects. 3. Compute the **Minkowski distance** between the two objects, using \( q = 3 \). 4. Compute the **supremum distance** between the two objects. ### 2.7 The median is one of the most important holistic measures in data analysis. Propose several methods for median approximation. Analyze their respective complexity under different parameter settings and decide to what extent the real value can be approximated. Moreover, suggest a heuristic strategy to balance between accuracy and complexity and then apply it to all methods you have given. ### 2.8 It is important to define or select similarity measures in data analysis. However, there is no commonly accepted subjective similarity measure. Results can vary depending on the similarity measures used. Nonetheless, seemingly different similarity measures may be equivalent after some transformation. Suppose we have the following 2-D data set: | A₁ | A₂ | |------|------| | x₁ | 1.5 | 1.7 | | x₂ | 2.2 | 1.9 | | x₃ | 1.6 | 1.8 | | x₄ | 1.2 | 1.5 | | x₅ | 1.5 | 1.0 | 1. Consider the data as 2-D data points. Given a new data point, \( x = (1.4, 1.6) \) as a query, rank the database points based on similarity with the query using Euclidean distance, Manhattan distance, supremum distance, and cosine similarity. 2. Normalize the data set to make the norm of each data point equal to 1. Use Euclidean distance on the transformed data to rank the data points. ### 2.7 Bibliographic Notes Methods for descriptive data summarization have been studied in the statistics literature long before the onset of computers. Good summaries of statistical descriptive data mining methods include Freedman, Pisani, and Purves [FP97] and Devore [Dev95]. #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 249 Context: ``` # INDEX LA 2901 - Editor, 173 LA 3001 - The Code, 132 LA 3610 - Digital Casting, 128 LA 3897 - The Expert constant genre, 132 LA 3909 - Multimedia, 83 LA 4100 - INDEX, 128 LA 4200 - Journalism, 31 LA 4400 - Crew, 211 LA 4800 - RACING, 60 LA 4810 - The Race for Eco, 104 LA 4811 - Bright Futures, 21 LA 4900 - Expert Panels, 65 LA 4910 - Create K-Philosophy, 125 LA 4915 - CPD Team Strategy, 211 LA 4916 - Hard-Edge Treatment, 15 LA 4917 - The Forum, 175 LA 4918 - Lush Buffalo, 12 LA 4920 - An Illustrated Man, 13 LA 4921 - Sources of Playings, 82 LA 4922 - Channeling Dust, 129 LA 4923 - Shopping Don’s Day, 128 LA 4930 - Exploration Herald, 202 LA 4237 - A.C.

1.3 Data mining—searching for knowledge (interesting patterns) in data.](image_path_here) Data mining, appropriately named "knowledge mining from data," which is unfortunately somewhat long. However, the shorter term, **knowledge mining** may not reflect the emphasis on mining from large amounts of data. Nevertheless, mining is a vivid term characterizing the process that finds a small set of precious nuggets from a great deal of raw material (Figure 1.3). Thus, such a misnomer carrying both "data" and "mining" became a popular choice. In addition, many other terms have a similar meaning to data mining—for example, *knowledge mining from data*, *knowledge extraction*, *data/pattern analysis*, *data archaeology*, and *data dredging*. Many people treat data mining as a synonym for another popularly used term, **knowledge discovery from data**, or **KDD**, while others view data mining as merely an essential step in the process of knowledge discovery. The knowledge discovery process is shown in Figure 1.4 as an iterative sequence of the following steps: 1. **Data cleaning** (to remove noise and inconsistent data) 2. **Data integration** (where multiple data sources may be combined)¹ ¹ A popular trend in the information industry is to perform data cleaning and data integration as a preprocessing step, where the resulting data are stored in a data warehouse. #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 23 Context: Additionally, we have a few other rules of thumb that are useful in programming contests: - \( 2^{10} = 1,024 \quad \text{and} \quad 2^{20} = 1,048,576 \). - Max 32-bit signed integer: \( \text{int} = 2^{31} - 1 \) (or use up to 9 decimal digits). - Max 64-bit signed integer: \( \text{long} = 2^{63} - 1 \). - Use `unsigned` if slightly higher positive number is needed (e.g., \( 2^{32} - 1 \)). - If you need to store integers \( \geq 2^n \), you need to use the Big Integer technique (Section 5.3). 1. Program with nested loops of depth \( k \) returning as little as possible has \( O(n^k) \) complexity. - If your program is recursive with recursive calls per level and has \( O(n^k) \) complexity, the problem has roughly \( O(n^k) \) complexity. But this is an upper bound. The actual complexity depends on what actions come later and whether some pruning are possible. 2. There are \( n! \) permutations and \( 2^n \) subsets (or combinations) of \( n \) elements. 3. Dynamic Programming algorithms which fill in a 2D matrix in \( O(n) \) per cell is \( O(n^2) \). - More details in Section 3 later. 4. The best time complexity of a comparison-based sorting algorithm is \( O(n \log n) \). 5. Most of the time, \( O(n \log n) \) algorithms will be sufficient for most contest problems. 6. The largest input size for typical programming contests problems must be \( < 1M \); because beyond that, the time needed to read the input (the I/O routine) will be the bottleneck. ### Exercise 1.2.2 Please answer the following questions below using your current knowledge about classic algorithms and their complexities. After you have finished reading this task book once, it may be beneficial to revisit this exercise again. 1. There are n webpages (1 ≤ n ≤ 10M). Each webpage has a different page rank \( r \). You want to pick the top 10 pages with highest page ranks. Which method is more feasible? - (a) Load all n webpages' page rank to memory, sort (Section 2.1), and pick the top 10. - (b) Use priority queue data structure (heap) (Section 2.2). 2. Given a list of up to 100 integers. You need to frequently ask the value of sum \( S_j \), i.e. the sum of \( L[j] + L[j+1] + ... + L[j+k] \). Which data structure should you use? - (a) Simple Array (Section 2.2.1). - (b) Simple Array that is pre-processed with Dynamic Programming (Section 2.2.1 & 2.5). - (c) Balanced Binary Search Tree (Section 2.2.2). - (d) Hash Table (Section 2.2.2). - (e) Segment Tree (Section 2.3.3). - (f) Route Tree (Section 2.4.3). - (g) Fastest Structure (Section 6.6). - (h) Suffix Array (Section 6.6.4). 3. Given a set \( S \) of points randomly scattered on 2D plane, \( N \leq 1000 \). Find two points \( S \) that has the greatest Euclidean distance. Is \( O(N^2) \) complete search algorithm that try all pairs possible? - (a) Yes, such complete search is possible. - (b) No, we must find another way. #################### File:

References to these libraries are available online at `www.openaig.com` and `java.com/javaref/docs/api`. Note that although these reference websites are usually given in programming contexts, we suggest that you try to master the syntax of the most commonly used libraries at the same time during the actual context! An exception to this practice is the *algorithm* of Balkan (a bitmap). This unusual data structure is important for certain types of data and for the efficiency of its algorithm. It is crucial for computer programmers as it plays a significant role in context. This data structure can be referenced to look a book: *Hacker's Delight* [1] and its details can be manipulated. External references for data structures mentioned in Section 2.2 are as follows: For Graph data structures, see [2] and Chapter 22 of [3]. For Union-Find data structures, see [4]. For Suffix Tree/Trie/Array in Section 6, see [5]. For Network Tree, see [6]. With more experience and by looking at sample codes, you will master more tricks in using these data structures. There are also data structures discussed in this book. The tri-based data structures (Suffix Tree/Trie/Array) in Section 6. Yet, there are still many other data structures that this book does not cover. If you want to dive into programming more, please study the mentioned data structures beyond what you read in this book. For example, AVL Tree, Red-Black Tree, or Splice Tree are useful for certain problem types where you need to implement and execute them efficiently [7]. Interval Tree which is similar to Segment Tree, (you have to find the approx space). Notice that some of the data structures shown in this book have the spirit of Divide and Conquer (discussed in Section 23). There are **117 UIs** (4 + 7 others) programming exercises discussed in this chapter. (Only 48 in the first edition, a 1985 version). There are **26 pages** in this chapter. (Only 12 in the first edition, a 507th version). ## Profile of Data Structure Inventors **Robert R. Floyd** (1939) has been Professor (emeritus) of Informatics at the Technical University of Munich. He invented the Red-Black (RB) Tree which is typically used in C++ STL, and Java etc. **Eugene A. Godel** (1906-1989) is a Soviet mathematician and computer scientist, along with Mikhail Nikiforovich Landa, he invented the AVL Tree in 1962. **Eymaelovich Landis** (1921-1997) was a Soviet mathematician. The name AVL Tree is attributed to introduce easy to traverse. Adede-Kwaki and Landis himself. **Peter M. Fuwick** is a Honorary Associate Professor in the University of Auckland. He invented Binary Search Tree in his original proposal for *computer based information processing* [8]. This has advanced the field in programming constructs material for efficient yet easy to implement data structure by his inclusion in the 101 syllabus [10]. ``` #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 161 Context: HAN10-ch03-083-124-97801238147912011/6/13:16Page124#42124Chapter3DataPreprocessingwasproposedinSiedleckiandSklansky[SS88].Awrapperapproachtoattributeselec-tionisdescribedinKohaviandJohn[KJ97].UnsupervisedattributesubsetselectionisdescribedinDash,Liu,andYao[DLY97].Foradescriptionofwaveletsfordimensionalityreduction,seePress,Teukolosky,Vet-terling,andFlannery[PTVF07].AgeneralaccountofwaveletscanbefoundinHubbard[Hub96].Foralistofwaveletsoftwarepackages,seeBruce,Donoho,andGao[BDG96].DaubechiestransformsaredescribedinDaubechies[Dau92].ThebookbyPressetal.[PTVF07]includesanintroductiontosingularvaluedecompositionforprincipalcom-ponentsanalysis.RoutinesforPCAareincludedinmoststatisticalsoftwarepackagessuchasSAS(www.sas.com/SASHome.html).Anintroductiontoregressionandlog-linearmodelscanbefoundinseveraltextbookssuchasJames[Jam85];Dobson[Dob90];JohnsonandWichern[JW92];Devore[Dev95];andNeter,Kutner,Nachtsheim,andWasserman[NKNW96].Forlog-linearmodels(knownasmultiplicativemodelsinthecomputerscienceliterature),seePearl[Pea88].Forageneralintroductiontohistograms,seeBarbar´aetal.[BDF+97]andDevoreandPeck[DP97].Forextensionsofsingle-attributehistogramstomultipleattributes,seeMuralikrishnaandDeWitt[MD88]andPoosalaandIoannidis[PI97].SeveralreferencestoclusteringalgorithmsaregiveninChapters10and11ofthisbook,whicharedevotedtothetopic.AsurveyofmultidimensionalindexingstructuresisgiveninGaedeandG¨unther[GG98].TheuseofmultidimensionalindextreesfordataaggregationisdiscussedinAoki[Aok98].IndextreesincludeR-trees(Guttman[Gut84]),quad-trees(FinkelandBentley[FB74]),andtheirvariations.Fordiscussiononsamplinganddatamining,seeKivinenandMannila[KM94]andJohnandLangley[JL96].Therearemanymethodsforassessingattributerelevance.Eachhasitsownbias.Theinformationgainmeasureisbiasedtowardattributeswithmanyvalues.Manyalterna-tiveshavebeenproposed,suchasgainratio(Quinlan[Qui93]),whichconsiderstheprobabilityofeachattributevalue.OtherrelevancemeasuresincludetheGiniindex(Breiman,Friedman,Olshen,andStone[BFOS84]),the #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 4 Context: # CONTENTS © Steven & Felix ## 7.2 2D Objects - 7.2.1 2D Objects: Circles ......................................... 181 - 7.2.2 2D Objects: Triangles ....................................... 183 - 7.2.3 2D Objects: Quadrilaterals ................................. 185 - 7.2.4 2D Objects: Spheres .......................................... 187 - 7.2.5 2D Objects: Others .......................................... 188 ## 7.3 Polygons with Literals - 7.3.1 Polygon Representation ....................................... 188 - 7.3.2 Parameter of a Polygon ..................................... 189 - 7.3.3 Area of a Polygon .......................................... 189 - 7.3.4 Checking if a Point is Inside a Polygon ................ 190 - 7.3.5 Cutting a Polygon with a Straight Line .................. 190 - 7.3.6 Finding the Convex Hull of a Set of Points .......... 191 - 7.3.7 Polygon and Conjugate Revisited ........................ 191 ## 7.4 Divide and Conquer Revisited ................................. 192 ## 7.5 Chapter Notes ..................................................... 195 # 8 More Advanced Topics ## 8.1 Overview and Motivation ....................................... 197 ## 8.2 Problem Decomposition - 8.2.1 Two Components: Binary Search the Answer and Other ... 197 - 8.2.2 Two Components: SSIP and DP ............................ 198 - 8.2.3 Two Components: Involving Graphs ........................ 199 - 8.2.4 Two Components: Involving Mathematics .................. 199 - 8.2.5 Three Components: Puzzle Factors, DP, Binary Search .. 200 - 8.2.6 Three Components: Complete Search, Binary Search, Greedy 201 ## 8.3 More Advanced Search Techniques - 8.3.1 Informed Search A* ........................................... 203 - 8.3.2 Depth Limited Search ......................................... 204 - 8.3.3 Iterative Deepening A* (IDA*) ............................ 204 ## 8.4 Advanced Dynamic Programming Techniques - 8.4.1 Emerging Technique: DP + Instruction .................. 206 - 8.4.2 Classic Functional Decomposition Problems ........... 207 - 8.4.3 Changes in Route/Response Problem ........................ 208 - 8.4.4 MLE/ILE: Use Better Slate Representation! ............... 209 - 8.4.5 “Make Your Deep One Parameter, Receive’ from Others!” 210 - 8.4.6 Your Parameter Values Go Negative?

An abridged edition has been prepared, however, for students who study the subject for only one semester and who do not care to purchase the larger text. It will be observed that the work includes two chapters on solid analytic geometry. These will be found quite sufficient for the ordinary reading of higher mathematics, although they do not pretend to cover the ground necessary for a thorough understanding of the geometry of three dimensions. It will also be noticed that the chapter on higher plane curves includes the more important curves of this nature, considered from the point of view of interest and applications. A complete list is not only unnecessary but undesirable, and the selection given in Chapter XII will be found ample for our purposes. ``` #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 72 Context: IntroductiontoDataMiningbyTan,Steinbach,andKumar[TSK05];DataMining:PracticalMachineLearningToolsandTechniqueswithJavaImplementationsbyWitten,Frank,andHall[WFH11];Predic-tiveDataMiningbyWeissandIndurkhya[WI98];MasteringDataMining:TheArtandScienceofCustomerRelationshipManagementbyBerryandLinoff[BL99];Prin-ciplesofDataMining(AdaptiveComputationandMachineLearning)byHand,Mannila,andSmyth[HMS01];MiningtheWeb:DiscoveringKnowledgefromHypertextDatabyChakrabarti[Cha03a];WebDataMining:ExploringHyperlinks,Contents,andUsage #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 72 Context: IntroductiontoDataMiningbyTan,Steinbach,andKumar[TSK05];DataMining:PracticalMachineLearningToolsandTechniqueswithJavaImplementationsbyWitten,Frank,andHall[WFH11];Predic-tiveDataMiningbyWeissandIndurkhya[WI98];MasteringDataMining:TheArtandScienceofCustomerRelationshipManagementbyBerryandLinoff[BL99];Prin-ciplesofDataMining(AdaptiveComputationandMachineLearning)byHand,Mannila,andSmyth[HMS01];MiningtheWeb:DiscoveringKnowledgefromHypertextDatabyChakrabarti[Cha03a];WebDataMining:ExploringHyperlinks,Contents,andUsage #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 72 Context: IntroductiontoDataMiningbyTan,Steinbach,andKumar[TSK05];DataMining:PracticalMachineLearningToolsandTechniqueswithJavaImplementationsbyWitten,Frank,andHall[WFH11];Predic-tiveDataMiningbyWeissandIndurkhya[WI98];MasteringDataMining:TheArtandScienceofCustomerRelationshipManagementbyBerryandLinoff[BL99];Prin-ciplesofDataMining(AdaptiveComputationandMachineLearning)byHand,Mannila,andSmyth[HMS01];MiningtheWeb:DiscoveringKnowledgefromHypertextDatabyChakrabarti[Cha03a];WebDataMining:ExploringHyperlinks,Contents,andUsage #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 167 Context: # Chapter 6 The Human Genome has approximately 3.3 Giga base-pairs — Human Genome Project ## 6.1 Overview and Motivation In this chapter, we present one more topic that is tested in ICPC — although not as frequent as graph and mathematics problems — namely, string processing. String processing is common in the research field of bioinformatics. However, as the strings that transcoders deal with can usually be extremely large, efficient data structures and algorithms are necessary. Some of these problems are presented as contest problems in ICPC. By mastering the content of this chapter, ICPC contestants will have a better chance at tackling these string processing problems. String processing tasks also appear in IOI, but usually they do not require variables, data structures, or may be simply string manipulations. Additionally, the input and output format tends to be less well-defined than in ICPC problems. IOI tasks that require string processing are usually still solvable using the problem solving paradigms mentioned in Chapter 1. Section 6.1 is drafting for students to solve string problems. Section 6.2 outlines basic string processing skills; however, we believe that it may be advantageous for IOI contestants to learn some of the more advanced material outside of their syllabuses. ## 6.2 Basic String Processing Skills We begin this chapter by listing several basic string processing skills that every competitive programmer must know. In this section, we provide a series of mini tasks that you should solve one after another without asking. You can use your favorite programming language (C, C++, or Java). Try your best to come up with the subtask, unless default implementations do it for you. ### 1. Given a string that only consists of lowercase alphanumeric characters [a-z,0-9], space, and period ('.'), write a program to read the text file from the user — encounter a long string first. When two lines are combined, give the output that the last word of the previous line is separated from the first of the current line. There can be up to 30 of any of your implementations can even give your implementation. Also read and store the last spaces at the end of each line. Note: The sample input file `file.txt` is shown on the next page: After question 1(a) and before task 2. --- (Original document might contain additional tasks or examples; ensure all tasks are addressed as needed.) #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 667 Context:

Given two objects represented by the tuples (22, 1, 42, 10) and (20, 0, 36, 8): 1. Compute the Euclidean distance between the two objects. 2. Compute the Manhattan distance between the two objects. 3. Compute the Minkowski distance between the two objects, using \( q = 3 \). 4. Compute the supremum distance between the two objects. ## 2.7 The median is one of the most important holistic measures in data analysis. Propose several methods for median approximation. Analyze their respective complexity under different parameter settings and decide to what extent the real value can be approximated. Moreover, suggest a heuristic strategy to balance between accuracy and complexity and then apply it to all methods you have given. ## 2.8 It is important to define or select similarity measures in data analysis. However, there is no commonly accepted subjective similarity measure. Results can vary depending on the similarity measures used. Nonetheless, seemingly different similarity measures may be equivalent after some transformation. Suppose we have the following 2-D data set: | | A₁ | A₂ | |-----|-------|-------| | x₁ | 1.5 | 1.7 | | x₂ | 2.2 | 1.9 | | x₃ | 1.6 | 1.8 | | x₄ | 1.2 | 1.5 | | x₅ | 1.5 | 1.0 | 1. Consider the data as 2-D data points. Given a new data point, \( x = (1.4, 1.6) \) as a query, rank the database points based on similarity with the query using Euclidean distance, Manhattan distance, supremum distance, and cosine similarity. 2. Normalize the data set to make the norm of each data point equal to 1. Use Euclidean distance on the transformed data to rank the data points. #################### File:

this chapter by asking you to solve the first problem type in ICPCs and IOIs: the Ad Hoc problems. According to [USACO, 29], Ad Hoc problems are problems that cannot be classified anywhere else, where each problem description and its corresponding solution are "unique." Ad Hoc problems are always appear in a programming contest. Using a benchmark of total problems, the first problem should be the easiest problem in an ICPC. If the problem is easy, it will be possible for the first problem assigned to be trivial in a programming context. But there exists Ad Hoc problems that are complicated to solve but seem trivial at first. For example, in the 2001 and 2002 ICPC, the first problem (day 1, problem A) was trivial, but in 2003 and 2004, the first task for each competition day started as only subtask 1. If you are in an ICPC with no straightforward problems, you will end up with only 3–5 challenging tasks. We believe that you can solve most of these problems yourself using advanced data structures or algorithms that will be discussed in the later chapters. Many of these Ad Hoc problems are "simple" but can be somewhat "tricky." Now, try to solve problems from each category before reading the next section! ## The categories: 1. **(Super) Easy** - You should start these problems **AC** in under 7 minutes each! - If you are just starting competitive programming, we strongly recommend that you start your journey by solving some problems from this category. 2. **Game (Card)** - There are a few Ad Hoc problems involving game theory. The first game type is related to cards. Usually you will need to parse the string input as normal cards (suits such as ♠, ♥, ♦, ♣). For example, inputs might include `2H`, `7D`, and `3S` applying to the usual rules: - 2 ≤ A, 3 ≤ 2, 3 ≤ Q, A ≤ K - It may be a good idea to map these complicated strings to integer values. For example, consider mappings to: - `2 ⇒ 3, 3 ⇒ 1, DA ⇒ 10, CA ⇒ 11, C3 ⇒ 12, H3 ⇒ 14, SA ⇒ 5, H1 ⇒ 13` 3. **Game (Chess)** - Another popular games that students express in programming contest problems are chess games. Some forms of Ad Hoc (listed in this section) don’t contain chess rules. Before you begin, note how many ways you can put queens in \( S \times S \) chess board (listed in Chapter 3). 4. **Game (Other)** - Other cards and game games, there are many other popular problems discussed that build on the fundamental tie-in to programming contest problems. The To-Do, Road-Paper-Stones, Graph-Makers, BINGO, Bursting, and many others. Keeping the details of these simple, notes of all of the rules and their uses are given in the problem description to avoid classifying contestants who have played these games before. Remember, you can read but you will not do it for others. Once you have read this section, don’t forget to try these problems and indeed super easy, "In some other arrangements, A < Z." #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page: 2 Context: # CONTENTS © Steven & Rix ## 3.4 Geometry 3.4.1 Examples 3.4.2 Dynamic Programming 3.4.3 DFS Illustration 3.5.1 DP Illustration 3.5.2 Classical Examples 3.5.3 Non Classical Examples ## 4 Graph 4.1 Overview and Motivation 4.2 Graph Traversal 4.2.1 Depth First Search (DFS) 4.2.2 Breadth First Search (BFS) 4.2.3 Finding Connected Components (in an Unrestricted Graph) 4.2.4 Finding Full Labeling/Chasing the Connected Components 4.2.5 Topological Sort of a Directed Acyclic Graph (DAG) 4.2.6 Bipartite Graph Check 4.2.7 Graph Edge Property Check via DFS Spanning Tree 4.2.8 Finding Articulation Points and Bridges (in an Undirected Graph) 4.2.9 Finding Strongly Connected Components (in a Directed Graph) 4.3 Minimum Spanning Tree 4.3.1 Overview and Motivation 4.3.2 Kruskal’s Algorithm 4.3.3 Prim’s Algorithm 4.4 Single-Source Shortest Paths 4.4.1 Overview and Motivation 4.4.2 Dijkstra’s Algorithm 4.4.3 SSP on Weighted Graph 4.4.4 SSP on Graph with Negative Weight Cycle 4.5 All-Pairs Shortest Paths 4.5.1 Overview and Motivation 4.5.2 Explanation of Floyd-Warshall’s DP Solution 4.5.3 Other Applications 4.6 Network Flow 4.6.1 Overview and Motivation 4.6.2 Ford Fulkerson’s Method 4.6.3 Edmonds-Karp’s 4.6.4 Other Applications 4.7 Special Graphs 4.7.1 Directed Acyclic Graph 4.7.2 Tree 4.7.3 Bipartite Graph ## 5 Mathematics 5.1 Overview and Motivation 5.2 All Bio Mathematics Problems 5.3 Basic Feature Class 5.3.1 Base Features 5.3.2 Base Features #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 27 Context: aybereadinorderofinterestbythereader.Advancedchaptersofferalarger-scaleviewandmaybeconsideredoptionalforinterestedreaders.Allofthemajormethodsofdataminingarepresented.ThebookpresentsimportanttopicsindataminingregardingmultidimensionalOLAPanalysis,whichisoftenoverlookedorminimallytreatedinotherdataminingbooks.Thebookalsomaintainswebsiteswithanumberofonlineresourcestoaidinstructors,students,andprofessionalsintheﬁeld.Thesearedescribedfurtherinthefollowing.TotheInstructorThisbookisdesignedtogiveabroad,yetdetailedoverviewofthedataminingﬁeld.Itcanbeusedtoteachanintroductorycourseondataminingatanadvancedundergrad-uatelevelorattheﬁrst-yeargraduatelevel.Samplecoursesyllabiareprovidedonthebook’swebsites(www.cs.uiuc.edu/∼hanj/bk3andwww.booksite.mkp.com/datamining3e)inadditiontoextensiveteachingresourcessuchaslectureslides,instructors’manuals,andreadinglists(seep.xxix). #################### File: A%20First%20Encounter%20with%20Machine%20Learning%20-%20Max%20Welling%20%28PDF%29.pdf Page: 29 Context: Chapter4TypesofMachineLearningWenowwillturnourattentionanddiscusssomelearningproblemsthatwewillencounterinthisbook.ThemostwellstudiedprobleminMListhatofsupervisedlearning.Toexplainthis,let’sﬁrstlookatanexample.Bobwanttolearnhowtodistinguishbetweenbobcatsandmountainlions.HetypesthesewordsintoGoogleImageSearchandcloselystudiesallcatlikeimagesofbobcatsontheonehandandmountainlionsontheother.SomemonthslateronahikingtripintheSanBernardinomountainsheseesabigcat....ThedatathatBobcollectedwaslabelledbecauseGoogleissupposedtoonlyreturnpicturesofbobcatswhenyousearchfortheword”bobcat”(andsimilarlyformountainlions).Let’scalltheimagesX1,..XnandthelabelsY1,...,Yn.NotethatXiaremuchhigherdimensionalobjectsbecausetheyrepresentallthein-formationextractedfromtheimage(approximately1millionpixelcolorvalues),whileYiissimply−1or1dependingonhowwechoosetolabelourclasses.So,thatwouldbearatioofabout1millionto1intermsofinformationcontent!Theclassiﬁcationproblemcanusuallybeposedasﬁnding(a.k.a.learning)afunctionf(x)thatapproximatesthecorrectclasslabelsforanyinputx.Forinstance,wemaydecidethatsign[f(x)]isthepredictorforourclasslabel.Inthefollowingwewillbestudyingquiteafewoftheseclassiﬁcationalgorithms.Thereisalsoadifferentfamilyoflearningproblemsknownasunsupervisedlearningproblems.InthiscasetherearenolabelsYinvolved,justthefeaturesX.Ourtaskisnottoclassify,buttoorganizethedata,ortodiscoverthestructureinthedata.Thismaybeveryusefulforvisualizationdata,compressingdata,ororganizingdataforeasyaccessibility.Extractingstructureindataoftenleadstothediscoveryofconcepts,topics,abstractions,factors,causes,andmoresuchtermsthatallreallymeanthesamething.Thesearetheunderlyingsemantic17 #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 43 Context: # Chapter 1 Introduction ![Figure 1.3 Data mining—searching for knowledge (interesting patterns) in data.](image_url) Data mining, appropriately named "knowledge mining from data," which is unfortunately somewhat long. However, the shorter term, **knowledge mining**, may not reflect the emphasis on mining from large amounts of data. Nevertheless, mining is a vivid term characterizing the process that finds a small set of precious nuggets from a great deal of raw material (Figure 1.3). Thus, such a misnomer carrying both "data" and "mining" became a popular choice. In addition, many other terms have a similar meaning to data mining—for example, **knowledge mining from data**, **knowledge extraction**, **data/pattern analysis**, **data archaeology**, and **data dredging**. Many people treat data mining as a synonym for another popularly used term, **knowledge discovery from data**, or **KDD**, while others view data mining as merely an essential step in the process of knowledge discovery. The knowledge discovery process is shown in Figure 1.4 as an iterative sequence of the following steps: 1. **Data cleaning** (to remove noise and inconsistent data) 2. **Data integration** (where multiple data sources may be combined) > A popular trend in the information industry is to perform data cleaning and data integration as a preprocessing step, where the resulting data are stored in a data warehouse. #################### File: Data%20Mining%20Concepts%20and%20Techniques%20-%20Jiawei%20Han%2C%20Micheline%20Kamber%2C%20Jian%20Pei%20%28PDF%29.pdf Page: 26 Context:

*Steven & Felix* Next, we continue our discussion with something light: the Ad Hoc string processing problems. They are programming and computer science problems involving string that require more than basic programming skills and perhaps some basic string processing skills discussed in Section 6.2 earlier. Here, we give a list of such Ad Hoc string processing problems with hints. These programming exercises have been further divided into sub-objects. ### Programming Exercises related to Ad Hoc String Processing: - **Cipher/Encode/Encrypt/Decode/Decrypt** - It is everyone’s wish that their private digital communications are secure. That is, their messages (or any) messages can only be read by the intended recipients. Many algorithms have been invented for this purpose, and some of them are very complicated; it is hard to contain it problems. This is interesting to learn a bit about Computer Security/Cryptography by solving similar problems. - **Frequency Count** - In this group of problems, the contestants are asked to count the frequency of a letter (say, base Direct Addressing Table) or a word (handle, the solution is the table using a balanced Binary Search Tree – the C++ STL map/Tree – or hash table). Some of the problems are related actually to Cryptography (the previous sub-category). - **Input Parsing** - This group of problems is best for I/O contestants as it enforces the input of I/O tasks to be formatted as simple as possible. However, there is no such restriction in IPC. Parsing problems range from simple forms that can be dealt with modified input regular, i.e. C/C++-style, to more complex problem involving using grammar's that requires extensive chaotic search or Java Parser class (Regular Expression). - **Output Formatting** - Another group of problems that is also not for I/O contestants. This time, the output is the problematic area. In an I/O problem, one might simply pass the output format as you might for the contestants. Practice your coding skills by solving these problems as you program for the contestants. - **String Comparison** - In this group of problems, the contestants are asked to compare strings with various criteria. This sub-category is similar to the string matching problems in the next section, but these problems may involve non-reciprocal functions. - **Ad Hoc** - These are other Ad Hoc string related problems that cannot be (or have not been) classified as one of the other sub categories above. --- *Note: It is important to understand that these programming problems focus on string processing but may require knowledge of other concepts such as the use of classes or recursive functions.* #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf

require one or combinations (see Section 3.2) of these problem-solving paradigms. In here, we have to nominate a chapter in this book that contestants have to really master, and we will discuss this more. The main source of the "Complete Search" material in this chapter is the USACO training gateway [2]. We adopt the term "Complete Search" rather than "Brute Force" as we believe that some "Complete Search" solutions can be cleaner and more refined, although it is complete. We refer to the term "Complete Search" as a self-referential term. We will discuss more advanced search techniques later in Section 3.8, A* Search, Depth Limited Search (DLS), Iterative Deepening (ID), and Iterative Deepening A* (IDA*). Divided and Conquer paradigms is usually stated in the form of its popular algorithm: binary search and its variants, merge/sort (face sort), and data structures: binary tree, heap, segment tree, etc. We will see more about this later in Computational Geometry (Section 7.4). Also, Greedy and Dynamic Programming (DP) techniques/executions are always included in popular algorithm textbooks, see Introduction to Algorithms [3], Algorithm Design [2], Algorithm [4]. However, to keep pace with the growing difficulties and clarity of these techniques, especially the DP techniques, we include more references from Introductory Textbooks and general programming contests in this book. We will revisit DP again for one occasion: First WishList’s DP algorithm (Section 6.7), PA (implied) DAG (Section 3.17), DP-String (Section 6.5), and more Advanced DPs (Section 5.4). However, for some real-life problems, especially those that are classified as NP-Complete [3], many of the approaches discussed so far will not work. For example, a Knapsack Problem with base O(N^5) complexity to know if sub bg P’s BG meets O(N^2 * K) complexity for b too slow if V is much larger than K. For such problems, people use heuristics or local search. Tabu Search [14], 4-Sourcer Algorithm, Ants Colony Optimization, Beam Search, etc. These are 19 UVA (4 + 15 other) programming exercises discussed in this chapter. (Only 10 in the first edition, a 75% increase.) There are 32 pages in this chapter. (Also 32 in the first edition, but some have been restructured to Chapter 4 and 8.) #################### File: Competitive%20Programming%2C%202nd%20Edition%20-%20Steven%20Halim%20%28PDF%29.pdf Page:
