NFA For any string x, there may exist none or more than one path from initial state and associated with x. For example − δ(q0,a)={q1} Q For example − δ(q0,a)={q1,q2} DFA is more difficult to construct. Since NFA can be one of many states after reading an input, the simulating DFA will have as its states the subsets of states of MN. A. We consider {S1,S2} as one state while converting €-NFA to DFA.
