Web2 Hopcroft and Karp’s algorithm for DFA In this section, we introduce (1) a notion of bisimulation for proving language equivalence of deterministic nite automata, (2) a naive algorithm that automat-ically checks language equivalence of DFA by mean of bisimulations (Section2.2) and (3) the standard Hopcroft and and Karp’s algorithm ... WebOct 28, 2015 · While this DFA works well, and for each accepting state it invokes the needed action correctly, the Hopcroft's algorithm for DFA minimization will merge the two accepting states into one which will result in a DFA with two states. This can be a problem because then we will not know which action to invoke in the accepting state.
