deterministic finite state machine

(definition)

Definition: A finite state machine with at most one transition for each symbol and state.

Also known as DFA, deterministic finite automaton.

See also nondeterministic finite state machine.

Note: Some fields, like model checking, require (and assume) that there is exactly one transition for each symbol and state. A machine that has at least one transition for each symbol and state is sometimes called "complete".
