Steven S. Skiena

Introduction to the design and analysis of computer algorithms. Topics include searching, sorting, data structures, dynamic programming, and graph algorithms. Time and space complexity. Upper-bound, lower-bound, and randomized analysis. Introduction to NP completeness.

MAT 211 or AMS 210; CSE 214

• Provide a rigorous introduction to worst-case asymptotic algorithm analysis.
• Develop classical graph and combinatorial algorithms for such problems as sorting, shortest paths and minimum spanning trees.
• Introduce the concept of computational intractability and NP completeness.
