## Theory of Computation

Theory of Computation. Instructor: Prof. Raghunath Tewari, Department of Computer Science and Engineering, IIT Kanpur. This is an introductory course on Theory of Computation intended for undergraduate students in computer science. In this course we will introduce various models of computation and study their power and limitations. We will also explore the properties of the corresponding language classes defined by these models and the relations between them. We will assume the student is comfortable in analytical reasoning and has preferably done a course on Data Structures and Algorithms.

Lecture 04 - Computation by DFA and Regular Operation |

In this lecture we will look at the formal definition of "what does it mean for a DFA to compute a string?". In the second half of the lecture we will define some binary and unary operation, called "Regular operation" applied on languages in order to obtain new language.
