: The connection between finite automata and regular expressions (patterns for matching strings) is established. The chapter proves the central theorem: the class of languages that can be described by regular expressions is exactly the same as those that can be recognized by finite automata. The process of converting between them is a major focus.

What makes An Introduction to Automata Theory and Formal Languages by Adesh K. Pandey stand out among competing textbooks (like those by Hopcroft, Ullman, or Peter Linz) is its student-centric approach:
