• Introduction to the Theory of Computation, 3rd Edition, Michael Sipser, Cengage Learning, 2012. (歐亞圖書代理)

This is an introductory course to the theory of computation. It covers various mathematical models, including automata and Turing machines, for physical computing machineries along with their computational capabilities/limitations. In terms of specific topics and the order of their exposition, the course will follow closely the book by Sipser.
(Note: a TA session will precede a class meeting whose date is marked with an *. There are four TA sessions on 3/25, 4/15, 5/20, and 6/10.)
