Expander Graph Application 2: Derandomization - Lecture 16c of CS Theory Toolkit

Explore the application of expander graphs in derandomization through this lecture from Carnegie Mellon University's graduate course "CS Theory Toolkit". Delve into how fully-explicit expander graphs can be utilized to decrease the error of randomized algorithms without significantly increasing the number of random bits used. Examine concepts such as error reduction, strongly explicit graphs, and algorithm analysis. Learn about random strings, set theory, and the magic trick of linear and exponential error decay in large expander graphs. Gain insights from resources like "Expander graphs and their applications" by Hoory, Linial, and Wigderson. Taught by Professor Ryan O'Donnell, this 23-minute lecture offers a comprehensive look at advanced topics in theoretical computer science.
