Automata theory is the study of abstract machines and computational problems which can be solved using these machines. These machines used in automata theory are known as automata. Automata theory also studies if there exist is any effective algorithms to solve a problem. Following are the list of various types of automata.

• Deterministic finite automata (DFA)
• Nondeterministic finite automata (NFA)
• Nondeterministic finite automata with ε-transitions (FND-ε or ε-NFA)
• Pushdown automata (PDA)
• Linear bounded automata (LBA)
• Timed automata
• Deterministic Buchi automata
• Nondeterministic Buchi automata
• Nondeterministic Rabin automata
• Deterministic Rabin automata
• Nondeterministic Streett automata
• Deterministic Streett automata
• Nondeterministic Parity automata
• Deterministic Parity automata
• Nondeterministic Muller automata
• Deterministic Muller automata

Each model in automata theory plays very significant roles in various applied fields. Finite automata are used in compilers, text processing, and hardware design.

General Outlook of Finite automata course

The branch of finite automata is an exciting, theoretical branch of computer science which is the basis for the theory of formal languages. The concept of the course is all about processes in which energy, materials and information are transmitted, transferred and utilized for different purposes without the direct participation of man. The key subjects in the study of Finite automata course includes Introduction to Finite Automata, Definition of DFA, Delta-star and Its Properties, Language Accepted by DFA, Properties of Regular Language, NFA, , NFA-Lambda, Language Accepted by NFA-Lambda, Conversion of NFA-Lambda to NFA, Conversion of NFA to DFA, Equivalence of NFA-Lambda and NFA, Kleene’s Theorem, Complement of Regular Language, Minimization of DFA, Application of FA, Simulation of FA, Non-Regular Languages, Myhill-Nerode Theorem, Pumping Lemma, Turing Machines, and so on. One of the main objectives of automata theory is to develop techniques by which scientists can illustrate and evaluate the vibrant deeds of discrete systems, in which signals are sampled periodically. The the performance will be determined based on the way that the system is constructed from storage and combinational elements.

Application of Finite automata course in technical studies

The various applications of automata theory in this technical world are Formal Grammar System, other Linguistics, Fluid Flow, Snowflake and crystal formation, Chaos theory, Cosmology, Financial analysis, various Biological aspects, and so on. The various theories of finite automata involves unbelievable stages of complexity, impossibly huge degrees of variation, and apparently random processes, so that it makes a logic that automata theory can contribute to a better scientific revolution. The unbeatable concepts behind the automatic transformation of an input in the presence of different states into the new processed output which are as per the different factual theorems is what formats the finite automata course as a new pearl to blossom the technical studies.
