CS 161: Design and Analysis of Algorithms – Spring 2015

Instructor: Virginia Vassilevska Williams
Time: Mondays and Wednesdays 11:00a-12:15p
Location: NVIDIA Auditorium


Worst and average case analysis. Recurrences and asymptotics. Efficient algorithms for sorting, searching, and selection. Data structures: binary search trees, heaps, hash tables. Algorithm design techniques: divide-and-conquer, dynamic programming, greedy algorithms, amortized analysis, randomization. Algorithms for fundamental graph problems: minimum-cost spanning tree, connected components, topological sort, and shortest paths. Introduction to network flows and graph matchings.


Before taking CS 161, it is important that you complete CS 103 and CS 109/STATS 116, or the equivalents.
In particular, you should be comfortable with proofs, discrete mathematics, basic graph and set theory, and introductory probability theory.
