This is an introductory course to the theory of computing, a study of formal/mathematical foundations of computer science and technology. Its goal is to acquaint the students with the basic concepts in computation theory and to cultivate the students' ability in analyzing the complexity of computational problems.

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

This introductory course to the theory of computing 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 03/16, 04/13, 05/18, and 06/08.)
