WebNFA is like multiple small machines that are performing computational activities at the same time. Rejection of string. DFA rejects the string in case it terminates in a state that is different from the accepting state. NFA rejects the string in the event of all branches dying or refusing the string. Backtracking.

WebMar 15, 2014 · Yes. For each state you can have multiple transitions. The ambiguity is due to (1) epsilon-transitions and (2) multiple transitions for a given state and symbol (like for s2 / a). So for each state and symbol you … WebDec 9, 2012 · 3. DFA must have a definite input symbol to move from one state to another state. Epsilon move isn't allow in DFA, because it'll change DFA into NFA. For e.g., suppose you are in state Q1, and you have a transition (Q1, e) = Q2, in this case you can directly go to Q2 without apply any input or you can stay in Q1 state, so you have two …

WebApr 2, 2015 · 2 Answers. You're right, your automaton describes 0*1*2*. q0 is where it handles a (possibly empty) series of 0s. q1 is where it handles a (possibly empty) series of 1s. By having an empty transition from q0 to q1, no character is needed between the 0s and the 1s. The empty transition does not let you describe any language that could not be ...
