This unit explores how regular expressions define languages accepted by finite automata. It includes essential theorems like Kleene’s Theorem and the Pumping Lemma , used to prove if a language is regular.
The book is frequently praised for having a large number of solved examples, which is crucial for mastering DFA design and TM construction.
Puntambekar’s book stands out because it is structured to follow the exact syllabus pattern of major Indian universities. While there are multiple editions for different course codes (like the SPPU 2019 Pattern or GTU 18 Course), the core content remains logically organized.

The final chapter addresses the fundamental limits of computation. Students are introduced to problems that are undecidable —problems for which no algorithm can possibly exist. The chapter uses the concept of recursive enumerability to introduce the halting problem and other undecidable problems like Post's Correspondence Problem (PCP) and The Class P and NP.
The textbook is a widely recommended academic resource for engineering and computer science students studying formal languages, automata, and complexity. Published by Technical Publications, this comprehensive book breaks down complex mathematical abstractions into easy-to-understand modules with a heavy focus on solved examples.
While the Theory of Computation is abstract, its implications are practical. Puntambekar’s text subtly reinforces this connection. By mastering the automata theory presented in her books, students gain the foundational knowledge necessary for compiler design, text processing, and hardware circuit design. The specific algorithms for DFA minimization or the construction of parse trees, often found in the core chapters of her book, are directly translatable to the optimization techniques used in real-world software engineering.

Formal language theory is a branch of the theory of computation that deals with the study of formal languages. A formal language is a set of strings of symbols that can be generated by a formal grammar. There are several types of formal languages, including:
A mathematical method used to find a regular expression from a given finite automaton state transition diagram.
