by Adesh K. Pandey is typically prescribed for undergraduate courses in Indian universities (VTU, JNTU, UPTU, Anna University, etc.). Unlike heavy theoretical tomes (e.g., Hopcroft & Ullman), Pandey’s book is known for its simplified exposition and problem-solving orientation . : Discusses the Chomsky Hierarchy , recursive function

Pandey’s book won’t replace the classic tomes, but it doesn’t need to. It serves as an excellent to automata theory—clear, practical, and exam-oriented. If you find yourself wanting deeper proofs or advanced topics, you can then graduate to Michael Sipser’s Introduction to the Theory of Computation . | | 3 | Regular Expressions & Languages
