Formal Languages and Computation: Models and Their Applicationsgives a clear, comprehensive introduction to formal language theory and its applications in computer science. It covers all rudimental topics concerning formal languages and their models, especially grammars and automata, and sketches the basic ideas underlying the theory of computation, including computability, decidability, and computational complexity. Emphasizing the relationship between theory and application, the book describes many real-world applications, including computer science engineering techniques for language processing and their implementation. Covers thetheory of formal languagesand their models, including all essential concepts and propertiesExplains how language models underlielanguage processorsPays a special attention toprogramming language analyzers, such asscannersandparsers, based on four language models-regular expressions, finite automata, context-free grammars, and pushdown automataDiscusses the mathematical notion of aTuring machineas a universally accepted formalization of the intuitive notion of a procedureReviews the generaltheory of computation, particularlycomputabilityanddecidabilityConsiders problem-deciding algorithms in terms of theircomputational complexitymeasured according to time and space requirementsPoints out that some problems are decidable in principle, but they are, in fact, intractable problemsfor absurdly high computational requirements of the algorithms that decide themIn short, this book represents a theoretically oriented treatment of formal languages and their models with a focus on their applications. It introduces all formalisms concerning them with enough rigors to make all results quite clear and valid.
