CS580
Algorithm Design, Analysis, and Implementation

Instructor: Tamal K. Dey
Content Description : In this course we will go through different paradigms for algorithm design such as divide-and-conquer, prune-and-search, dynamic progamming, greedy strategy, randomization, linear programming, approximation and different analysis techniques with different data structures. We will apply these design and analysis techniques to develop efficient graph and other algorithms. At the end, we will go over the concept of NP-completeness.
Objectives

Be familiar with topics in algorithms such as the ones listed above
Be familiar with how to design algorithms for problems with techniques listed above
Master a subset of algorithms: graph algorithms, linear programming, approximation algorithms
Be familiar with how to research the background of a topic in algorithms

Prerequisites: CS381; or grad standing and permission of instructor
Recommended Books:

Algorithm Design, J. Kleinberg and E. Tardos, Pearson, Addison-Wesley
Introduction to Algorithms, T. Cormen, C. Leiserson and R. Rivest, MIT press, McGraw-Hill Book Company.

Class discussion:

This term we will be using Piazza for class discussion. The system is highly catered to getting you help fast and efficiently from classmates, the TA, and instructors. Rather than emailing questions to the teaching staff, we encourage you to post your questions on Piazza.
