Algorithms and Complexity
CS 331, Fall 2024

Description

This course is a comprehensive introduction to the design and analysis of algorithms. Our goal is to investigate strategies for answering: how efficiently can we complete a given computational task? After this course, students should be equipped to tackle this question for a wide range of fundamental tasks arising in the practice of computer science.

The first three units of this course cover common algorithmic paradigms, familiarizing students with the principles of recursion, dynamic programming, and greedy algorithms. The next three units introduce toolkits for designing graph algorithms, continuous algorithms, and randomized algorithms, emphasizing real-world applications. The last unit, complexity theory, develops techniques for reasoning about fundamental limits on computational efficiency.
