Deterministic automaton
In computer science, a deterministic automaton is a concept of automata theory in which the outcome of a transition from one state to another is determined by the input.
A common deterministic automaton is a deterministic finite automaton which is a finite state machine where for each pair of state and input symbol there is one and only one transition to a next state. DFAs recognize the set of regular languages and no other languages.
A standard way to build a deterministic finite automaton from a nondeterministic finite automaton is the powerset construction.
