Algorithm design and analysis is fundamental to all areas of computer science and gives a rigorous framework for the study of optimization. This course provides an introduction to algorithm design through a survey of the common algorithm design paradigms of greedy optimization, divide and conquer and dynamic programming. More advanced topics covered in the course include network flows, NP-completeness, linear programming, approximation algorithms, etc.

Required Textbook

Jon Kleinberg and Eva Tardos    Algorithm Design.   1st Edition, 2005, Pearson.
