This is a theory course and we will assume that you are comfortable with mathematical proofs. We recommend that you have taken a theory of computation course (e.g., CS 353) and an algorithms course (e.g., CS 331). A basic understanding of probability theory (e.g., MATH 362K) and modular arithmetic will also be helpful.

Reference Material

Throughout the semester, we will post additional reference material here:


The structure and material of this course is inspired by Stanford's CS 255 and CS 355 courses.
