That is a string is accepted by a DFA if and only if the DFA starting at the initial state ends in an accepting state after reading the string.A language L is accepted by a DFA ( Q , , q0 , , A ) , if and only if L = { w | *( q0 , w ) A } . That is, the language accepted by a DFA is the set of strings accepted by the DFA. machine accepts w if the last input of w causes the machine to halt in one of the accepting states. Otherwise, it is said that the automaton rejects the string. We say the string w is accepted if, proceeding from the start state, the terminal state we reach is final i.e., ∈ F. Concisely, w is accepted if δ*(s,w) ∈ F. Because of the determinism, it is sometimes said that w is decided by a DFA. The language accepted by a DFA is the set of all strings accepted by a DFA.DFA and Regular Language Equivalence Theorem: A language is accepted by a DFA if and only if it is a regular language (i.e., has a regular expression). finite automata examples lecture notes finite automata non deterministic finite automata regular expression pushdown automata finite automata tutorial deterministic finite automata nondeterministic finite automata lecture notes finite automata finite automata examples ppt what is finite automata nondeterministic finite automata examples finite automata tutorial finite automata examples with solution deterministic finite automata solved examples finite automata examples pdf pushdown automata examples pushdown automata solved examples pushdown automata tutorial turing machine pushdown automata pdf pushdown automata ppt pushdown automata notes context free grammar example automata deterministic finite automata tutorial finite automata examples how to draw finite automata difference between finite automata transition graph probabilistic finite state automata dfa tutorial finite state automata examples deterministic finite automata solved examples deterministic finite automata problems with solutions deterministic finite automata examples difference between dfa and nfa deterministic finite automata tutorial non deterministic finite automata deterministic finite automata problems deterministic finite automata pdf nondeterministic finite automata examples nondeterministic finite automata tutorial nondeterministic finite automata problems nondeterministic finite automata ppt nondeterministic finite automata to deterministic difference between deterministic and nondeterministic finite automata nondeterministic finite automata exercises nondeterministic finite automata regular expression learning regular languages non deterministic finite automata non deterministic finite automata examples nondeterministic finite automata examples pdf nondeterministic finite automata applications nondeterministic finite automata ppt nondeterministic finite automata are more powerful than deterministic finite automata nondeterministic finite automata to deterministic finite automata nondeterministic finite automata to regular expression finite automata tutorial automata theory questions answers pdf finite automata examples lecture notes finite automata automata theory lecture notes finite automata and formal languages notes finite automata and formal languages formal language and automata theory
