WebMar 12, 2024 · 1 Answer. Well, as I understand it, the algorithm to produce an equivalent DFA for an NFA takes as the set of states of the DFA the power set of the set of states of the NFA; that is, if our NFA has states q0 and q1, our DFA will have states {}, {q0}, {q1}, {q0, q1}. Then, we add the productions as follows: if the NFA has a transition from q to ... WebJan 28, 2024 · Here we address the question of what happens if a DFA has empty alphabet?
