![]() With the invent of new technologies many new developments are seen in this field. Automata have been around since the prehistoric period. In this article, we have learned a brief introduction to the automata theory languages and computation. In theory of finite fields also we can find the application of Automata.In the field of biology, Cellular automata are useful.For applications in AI and in programming languages, Context-free grammar is very useful.For text processing compilers and hardware designs, finite automata play a major role. Non Deterministic Finite Automata or NFA is an automata in which for some current state and input symbol, there exists more than one next output states.Automata theory is very useful in the fields of Theory of computation, compiler productions, AI, etc.The applications of automata theory include the following. The transitions are Graphical Representation Tabular Form State Diagram State Diagram of Non-Deterministic Finite Automata Automata Theory Applications Let the Non-Deterministic Finite Automata be. Non-deterministic finite automata are represented with the help of the state diagram. Non-deterministic Finite Automata is represented as the set of 5 –tuple where(Q ,∑,δ,qo , F) It is also called Non-Deterministic Finite Automata, as it has a finite number of states. The automata where the output state for the given input cannot be determined is called Non-Deterministic Automata. The state with double circles is the final state.:S× P(S) : S × ( S) is a function called the transition. is the alphabet (defining what set of input strings the automaton operates on), 3. ![]() ![]() 1 2 Thus, the probabilistic automaton also generalizes the concepts of a Markov chain and of. S S is a non-empty finite set of states, 2. In mathematics and computer science, the probabilistic automaton ( PA) is a generalization of the nondeterministic finite automaton it includes the probability of a given transition into the transition function, turning it into a transition matrix. The empty single incoming arc represents the initial state. A non-deterministic finite automaton (or NDFA) can be formally defined as a 5-tuple (S,q0,F) ( S,, , q 0, F), where.Transitions are represented by the arc labeled with an input alphabet.The states are represented by vertices.State Diagram of Deterministic Finite State Automata For example, for the set Σ = and the transition function be Graphical Representation Tabular Form Kleen Star: It is the unary operator on the set of symbols Σ, which gives the infinite set of all the possible strings, including λ, of all the possible lengths over the set Σ.
