automata theory, body of physical and logical principles underlying the operation of any electromechanical device (an automaton) that converts information from one form into another according to a definite procedure.
An automaton (Automata in plural) is an abstract self-propelled computing device which follows a predetermined sequence of operations automatically. An automaton with a finite number of states is called a Finite Automaton (FA) or Finite State Machine (FSM).
We begin with a study of finite automata and the languages they can define the so-called "regular languages." Topics include deterministic and nondeterministic automata, regular expressions, and the equivalence of these language-defining mechanisms.

What is Automata Theory? Study of abstract computing devices, or “machines” Automaton = an abstract computing device A fundamental question in computer science is: Finding out what different models of machines can do and cannot do The theory of computation Computability vs. Complexity
Advanced Automata Theory is a lecture which will rst review the basics of formal languages and automata theory and then give insight into speci c topics from wider area of automata theory. In computer science, automata are an important tool for many theoretical results and various types of automata have been used to characterise complexity classes.
Jan 11, 2020 · Automata theory is the branch of computer science that is concerned with the study of abstract machines and automata. These include finite-state machines, pushdown automata and Turing machines. Finite-state machines are abstract machines that may be in one of a finite number of states.
Jan 19, 2022 · The book is a concise, self-contained and fully updated introduction to automata theory – a fundamental topic of computer sciences and engineering. The material is presented in a rigorous yet convincing way and is supplied with a wealth of examples, exercises and down-to-the earth convincing explanatory notes.
Automata theory - Finite, Pushdown, Turing: All automata referred to from this point on may be understood to be essentially Turing machines classified in terms of the number, length, and movement of tapes and of the reading and writing operations used.
