This video lecture on DFA to Regular Expression, a core conversion topic of Automata Theory and Theory of Computation, is designed for BTech 3rd Year Computer Science and IT students. In this lecture, we explain methods to convert a DFA into an equivalent regular expression, including state elimination technique and systematic reduction, with step-by-step explanation and exam-oriented approach.

This lecture is especially useful for RGPV BTech 3rd Year students from branches such as CSE, IT, AIML, DS, and is equally relevant for students of AKTU, VTU, GTU, JNTU, SPPU, Anna University, and other Indian engineering universities. The explanation is procedural, logical, and exam-focused, making it ideal for Theory of Computation Unit 2 preparation and semester revision.

📘 This Theory of Computation Playlist Will Include:

Introduction to Set Theory
Basic Terms of Automata Theory
Introduction to Automata Theory
Finite State Automata
Deterministic Finite Automata (DFA)
Non-Deterministic Finite Automata (NFA)
Epsilon NFA & Epsilon Closure
Regular Expression
Identities of Regular Expression
Regular Expression Numericals

Understanding DFA to Regular Expression conversion is essential for regular language characterization, compiler design, and solving high-weightage conversion problems in Theory of Computation exams. This lecture is also useful for B.Sc., M.Sc., B.Tech, and M.Tech students, and for those preparing for higher studies and competitive examinations.
