Title: Great introduction to theory of computing
Review: I read it during my undergraduate, it was the course book for the thoery of automata course. More recently when I tried the popular "Introduction to Automata Theory, Languages, and Computation" by Hopcroft et al. for the purpose of revising the concepts, I realized how great this book is. It is definitely a better book than Hopcroft et al's, with in-depth explanations of all topics, lots of examples and exercises and in a writing style very friendly for the novice readers. Very good work!
