2 3 EQUIVALENCE OF NFA AND DFA Every time we find that if we are constructing an automata, then it is quite easy to form an NFA instead of DFA So, it is necessary to convert an NFA into a DFA and this is also said to be equivalence of two automata Two finite automata M and N are said to be equivalent if L(M) = L(N)
