"Languages and Machines introduces the foundations of computer science and examines the capabilities and limitations of algorithmic computation. With an expanded selection of topics, the Third Edition features a wealth of examples, illustrations, and practical applications alongside the presentation of the theoretical concepts." This student-friendly, mathematically sound presentation assumes no advanced prerequisites. The flexible design of the text allows instructors to structure their course around formal language and automata theory, computability, computational complexity, or the use of formal languages in programming language definition and parsing. This revied edition of a mathematically sound presentaion of the theoretical aspects of computing includes step-by-step, unhurried proofs, worked-out examples that demonstrate theoretical concepts, and numerous diagrams and line drawings which highlight the underlying concepts.
