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; a transition function δ : Q × Σ → Q; 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 … WebIf you want a regular expression for this language, you can proceed as follows First compute the minimal DFA of L ( u) (this automaton has u + 1 states). Compute the minimal DFA of its complement (just swap the final states and the non final ones). Compute a regular expression from the resulting DFA.
