WebIn fact, this theorem is at the heart of e cient DFA minimization algorithms. Here we present the Myhill-Nerode theorem, and give some examples applying it to both regular and non-regular languages. We also use this theorem to prove that there are languages for which the minimal DFA for a language has exponentially more states than Webreﬁnement was needed for the constructive formulation of the Myhill-Nerode theorem.

WebDFA minimization. In general, the DFA generated by this procedure may have more states than necessary. According to the Myhill–Nerode theorem, there is a unique minimal DFA that accepts the same input as a given DFA. This minimal DFA can be found by merging together the reachable states of the original DFA that are equivalent to each other. Webnumber of states in a DFA which recognizes L if L is regular.
