Introduction to Automata Theory, Languages and Computation by Hopcroft, Motwani, and Ullman is another comprehensive text. The job of a Finite Automaton is to accept or reject an input depending on whether the pattern defined by it occurs in the input. Theory of computation is the branch that deals with how efficiently problems can be solved on a model of computation, using an algorithm. ‘Theory of Computation’ or ‘Theory of Automata’ is the core area of computer science and engineering; it is the branch that aims to attempts the deep understanding of computational processes by means of effectively solving the problems via mathematical models, tools, and techniques. K An automaton with a finite number of states is called a Finite automaton. More of your questions answered by our Experts. Theory of Computation 68 views Finite automata (FA) is a simple idealised machine used to recognize patterns within input taken from some character set.
