WebOne algorithm for merging the nondistinguishable states of a DFA, due to Hopcroft (1971), is based on partition refinement, partitioning the DFA states into groups by their behavior. These groups represent equivalence classes of the Myhill–Nerode equivalence relation , whereby every two states of the same partition are equivalent if they have the same … WebNFA DFA (subset construction) • Build the simulation DFA Minimal DFA • Hopcroft’s algorithm DFA RE (Not part of the scanner construction) • All pairs, all paths problem • Take the union of all paths from s 0 to an accepting state minimal DFA RE NFA DFA The Cycle of …
