WebFormal definition. A deterministic finite automaton M is a 5-tuple, (Q, Σ, δ, q 0, F), consisting of . a finite set of states Q; a finite set of input symbols called the alphabet Σ; an initial or start state; a set of accept states; Let w = a 1 a 2 …a n be a string over the alphabet Σ.The automaton M accepts the string w if a sequence of states, r 0, r 1, …, r … WebDec 27, 2015 · There is no sensor that indicates which state is actually chosen. The interpretation often given in the theory of computation is that when there are multiple choices, the machine clones itself and one copy runs each choice. It is like having multiple universes in which each different possible action of nature is occurring simultaneously.
