COMS 4231: Analysis of Algorithms I, Fall 2010 Problem Set 6, due Tuesday December 7, in class Note: We plan to post solutions on Tuesday after the class, in preparation for the final, so no late homeworks will be accepted. Please follow the homework submission guidelines posted on the web As usual, for each of the algorithms that you give, include an explanation of how the algorithm works, why it is correct, what is its running time, and why it has the claimed running time. Problem 1 . a. Exercise 24.3-2 in CLRS, page 663. b. Exercise 24.3-4 in CLRS, page 663. Problem 2. Do Problem 24-1 in CLRS, page 678. Problem 3 . Do Problem 26-3 (“Algorithmic consulting”) in CLRS, page 761. Problem 4 . The Maximum Independent Set (MIS) problem is as follows: Given an undirected graph G=(N,E), find a maximum-size set S of nodes that are pairwise non- adjacent, i.e. there is no edge connecting any two nodes of S (such a set of nodes is called independent). 1. Give an efficient algorithm to solve the MIS problem when G is bipartite.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
