Videos Part 1 Full playlist Why Study Algorithms? Section 1. TSP: An Algorithmic Mystery Section Magic Boxes Section Test Cases and Data Sets for Programming Projects General advice: use the small test cases to help debug your program before tackling the challenge data set. Programming Problem 1. Challenge problem: What is the product of and ?
Programming Problem 3, algorithms illuminated pdf download. Test case: This file contains 10 integers, representing a element array. Your program should count 28 inversions in this array.
Challenge data set: This file contains all of the integers between 1 andinclusive in some order, with no integer repeated. The ith row of the file indicates the ith entry of an array, algorithms illuminated pdf download. How many inversions does this array have? Obviously, to get the most out of this assignment, you should implement the fast divide-and-conquer algorithm from Section 3. Programming Problem 5. Your program should count 25 comparisons if you always use the first element as the pivot, 31 comparisons if you always use the last element as the pivot, and 21 comparisons if you algorithms illuminated pdf download use the median-of-3 as the pivot not counting the comparisons used to compute the pivot.
Test case 2: This file contains integers, algorithms illuminated pdf download a element array. Your program should count comparisons if you always use the first element as the pivot, comparisons if you always use the last element as the pivot, and comparisons if you always use the median-of-3 as the pivot not counting the comparisons used to compute the pivot.
Challenge data set: This file contains all of the integers between 1 and 10, inclusive in some order, with no integer repeated. How many comparisons does QuickSort make on this input when the first element is always chosen as algorithms illuminated pdf download pivot?
If the last element is always chosen as the pivot? If the median-of-3 is always chosen as the pivot? Programming Problem 6. What is the median i, algorithms illuminated pdf download. Solution: Challenge data set: Form an array in which the first element is the first 10 digits of pi, the second element is the next 10 digits of pi, algorithms illuminated pdf download, and so on.
The digits of pi are available here. Make the array as big as you can perhapselements, or 1 million elements, or What is the median of the array? For the challenge data set above, compare the maximum array lengths solvable in a reasonable amount of time e. Programming Problem 8. Top 5 SCC sizes: 3,3,3,0,0 Test case 2: An 8-vertex edge graph. Top 5 SCC sizes: 3,3,2,0,0 Test case 3: An 8-vertex 9-edge graph.
Top 5 SCC sizes: 3,3,1,1,0 Test case 4: An 8-vertex edge graph. Top 5 SCC sizes: 7,1,0,0,0 Test case 5: A vertex edge graph. Top 5 SCC sizes: 6,3,2,1,0 Challenge data set: This file describes the edges of a directed graph.
Vertices are labeled as positive integers from 1 to Each row indicates one edge of the graph the tail and head vertices, algorithms illuminated pdf download, in that order.
For example, the eleventh row "2 " indicates that there is an edge directed from vertex 2 to vertex What are the sizes of the biggest five strongly connected components? Programming Problems 9. What are the shortest-path distances from vertex 1 to every other vertex?
Answer, algorithms illuminated pdf download, for vertices 1 through 8, in order: 0,1,2,3,4,4,3,2. Challenge data set: This file contains an adjacency list representation algorithms illuminated pdf download an undirected graph with algorithms illuminated pdf download labeled 1 to Each row indicates the edges incident to the given vertex along with their nonnegative lengths.
For example, the sixth row has a "6" as its first entry indicating that this row corresponds to vertex 6. The next entry of this row "," indicates that there is an undirected edge between vertex 6 and vertex that has length The rest of the pairs in this row indicate the other vertices adjacent to vertex 6 and the lengths of the corresponding edges. Vertex 1 is the starting vertex. What are the shortest-path distances from vertex 1 to the following ten vertices? Programming Problem What are the last 4 digits of the sum of the kth medians?
See below for the definition of the kth median. Answer: Challenge data set: This file contains a list of the integers from 1 to in unsorted order; you should treat this as a stream of numbers, arriving one by one. What are the last 4 digits of the sum of the kth medians with k going from 1 to ?
Which data structure makes your algorithm faster: two heaps, or a search tree? Note: ensuring distinctness requires a one-line addition algorithms illuminated pdf download the algorithm in Section Answer: 8 Challenge data set: This file contains one million integers, both positive and negative possibly with repetitions! What is the weighted sum of completion times of the schedule output by the GreedyDiff and GreedyRatio algorithms?
Break ties in favor of jobs with larger weights. Answer: andrespectively. Challenge data set: Repeat the previous problem with the set of jobs listed in this file. Test cases: contributed by Rupendra Bandyopadhyay For the and symbol problem instances described in test case 1 and test case 2what is the minimum and maximum length of a codeword in the corresponding optimal prefix-free code?
Answer: 2 and 5 for test case 1, 3 and 6 for test case 2. Challenge data set: Repeat the previous problem with the symbol problem instance described in this file. Edge costs can be negative, and are not necessarily distinct. Test case: contributed by Quentin Appleby What is the cost of an MST in the graph described in this file? Answer: 14 Challenge data set: Repeat the previous problem for the graph described in this file.
Which algorithm has a faster straightforward implementation, Prim's or Kruskal's algorithm? Which is faster, the heap-based implementation of Prim's algorithm or the union-find-based implementation of Kruskal's algorithm?
Test case: contributed by Logan Travis What is the value of a maximum-weight independent set of the vertex path graph described in this fileand which vertices belong to the MWIS? Answer:and the vertices 2, 4, 7, and Challenge data set: Repeat the previous algorithms illuminated pdf download for the vertex path graph described in this file.
You can assume that all numbers are positive. You should assume that item weights and the knapsack capacity are integers. Test case: What is the value of an optimal solution to the knapsack instance described in this file? Answer: Challenge data set: Repeat the previous problem for the knapsack instance described in this file.
This instance is so big that the straightforward iterative implementation described in the book uses an infeasible amount of time and space. So you will have to be creative to compute an optimal solution, algorithms illuminated pdf download. One idea is to go back to a recursive implementation, solving subproblems and, of course, algorithms illuminated pdf download, caching the results to avoid redundant work only on an "as needed" basis.
Also, be sure to think about appropriate data structures for storing and looking up solutions to subproblems. The format of the file is: 1st line: length of X and length of Y 2nd line: gap cost and mismatch cost the latter is the same for every pair of distinct symbols 3rd line: X sequence 4th line: Y sequence Answer: the NW score is The format of the file is: 1st line: number specifying the number n of keys 2nd line: n frequencies as comma-separated integer values Answer: the value of an optimal solution is The first line of the file indicates the number of vertices and edges, respectively.
Each subsequent line describes an edge the first two numbers are its tail and head, algorithms illuminated pdf download, respectively and its length the third number.
NOTE: edge lengths might be negative, and the graphs may or may not be negative cycles. Test cases: contributed by Matt Davis What is the shortest shortest path in the graphs decribed in this file and in this file? If the graph has a negative cycle, your algorithm should detect that fact, algorithms illuminated pdf download. Answer: -2 and "contains a negative cycle," respectively. Challenge data set: Repeat the previous problem for the graphs described in the following files: graph 1graph 2graph 3and graph 4.
Programming Problems Format 2: for Euclidean instances The first line indicates the number of vertices. Each vertex is a point in the plane, and each subsequent line indicates the x- and y-coordinates of a single vertex. The cost of the edge between two vertices is then the Eulidean distance between its endpoints. Test case 1: This file describes the instance in Quiz Optimal tour cost: 13 Test case 2: This file describes the instance in Quiz Optimal tour cost: 23 Test case 3: contributed by Eric Hulburd This file describes an 8-vertex Euclidean instance in format 2.
