WebShow for any state $q$, string $x$, and input symbol $a$, $\hat\delta(q, ax) = \hat\delta(\delta(q, a), x)$, where $\hat\delta$ is the transitive closure of $\delta$, which … WebThe transition function of the DFA maps a state S (representing a subset of Q) and an input symbol x to the set T(S,x) = ∪{T(q,x) q ∈ S}, the set of all states that can be reached by an x-transition from a state in S. A state S of the DFA is an accepting state if and only if at least one member of S is an accepting state of the NFA.
Webstates. : Q !Qis a transition function (i.e., for each q2Q, a2, (q;a) is the next state of the DFA when processing symbol afrom state q) Given a state and a single input symbol, a transition function gives a new state. Extended transition function (q;s) gives new state for DFA after processing string s2 starting from state q2Q. It can be WebNFA also has five states same as DFA, but with different transition function, as shown follows: δ: Q x ∑ →2 Q. where, Graphical Representation of an NFA.
