Introduction to Automata Theory, Languages, and Computation (2nd Edition)

"This classic book on formal languages, automata theory, and computational complexity has been updated to present theoretical concepts in a concise and straightforward manner with increased coverage of practical applications. This third edition offers students a less formal writing style while providing the most accessible coverage of automata theory available, solid treatment on constructing proofs, many figures and diagrams to help convey ideas, and sidebars to highlight related material. A new feature of this edition is Gradiance, a Web-based homework and assessment tool. Each chapter offers an abundance of exercises, including selected Gradiance problems, for a true hands-on learning experience for students."--BOOK JACKET. It has been more than 20 years since this classic book on formal languages, automata theory, and computational complexity was first published. With this long-awaited revision, the authors continue to present the theory in a concise and straightforward manner, now with an eye out for the practical applications. They have revised this book to make it more accessible to today's students, including the addition of more material on writing proofs, more figures and pictures to convey ideas, side-boxes to highlight other interesting material, and a less formal writing style. Exercises at the end of each chapter, including some new, easier exercises, help readers confirm and enhance their understanding of the material. This title seeks to present automata theory in a simple and straightforward manner. It includes material on writing proofs, figures and pictures to convey ideas, side boxes to present supplemental material, and program-like notation for PDAs and Turing machines.
