EECS 574: Computational Complexity (Fall 2021)

Overview: This course explores the story of computation after Alan Turing. The notion of Turing Machines provides a mathematical abstraction of what it means to compute. In principle, it captures all computing devices that we know of or will ever come up with. Computational complexity takes a step further and also takes into consideration the fact that computers are limited in resources, such as time, memory, or randomness. The phenomenon of computing becomes much more nuanced with limited resources in mind. Which computational problems can or cannot be solved with limited resources? That is what computational complexity aims to study.
