FORMAL LANGUAGES & AUTOMATA THEORY BY SUNITHA PDF

F is a set of states of Q i. Input word An automaton reads a finite string of symbols a1,a2, Run A sequence of states q0,q1,q2, In other words, at first the automaton is at the start state q0, and then the automaton reads symbols of the input word in sequence. Recognized language An automaton can recognize a formal language. Recognizable languages The recognizable languages are the set of languages that are recognized by some automaton.

I assume basic knowledge of discrete mathematics, only. In particular, it may be helpful if the reader has a basic understanding of what constitutes a proof of a mathematical assertion. All the remaining material is introduced in the text. Fundamental concepts are exemplified, too. I am strongly convinced that a solid compromise between formal correctness and intuitive ideas may help both the students and instructors to enjoy the wealth of insight this book is aiming to present.

Main emphasis is put on the interaction of theory and practice in informatics. Theory must deal with problems of practical importance and practical informatics needs a solid foundation to develop its full potential.

Therefore, two thirds of the book are devoted to formal languages and automata theory. Formal languages are indispensable for applied computer science, since one meets them everywhere. Thus, i cover grammars formalizing the generation , automata formalizing the acceptance and their interaction for regular and context-free languages.

The remaining third formalizes the intuitive notion of algorithm by introducing partial recursive functions and Turing machines. We show the equivalence of these two models and prove the existence of a universal Turing machine. That is, there is one computing device that can perform every possible computation. Finally, i show that there are problems which cannot be solved at all by any computer.

The book contains an in-depth coverage of all the topics related to the theory of computation as mentioned in the syllabuses of B. Computer Science of various universities. Sufficient amount of theoretical inputs supported by a number of illustrations are included for those who take deep interest in the subject.

In the first few chapters, the book presents the necessary basic material for the study of automata theories. This book facilitates students a more informal writing style while providing the most accessible coverage of automata theory, solid treatment on constructing proofs, many figures and diagrams to help convey ideas, and sidebars to highlight related material.

Each chapter offers an abundance of exercises for hands-on learning.
