WebPowerset construction. In the theory of computation and automata theory, the powerset construction or subset construction is a standard method for converting a nondeterministic finite automaton (NFA) into a deterministic finite automaton (DFA) which recognizes the same formal language. It is important in theory because it establishes that NFAs ...

WebDFA. The best known algorithm for this procedure runs in O(knlogn)time [9], for a DFA with n states over an alphabet of k symbols. Hopcroft and Karp [10] proposed an algorithm for testing the equivalence of two DFAs that makes use of an almost O(n) set merging method.

WebHopcroft's Algorithm for DFA minimization Hopcroft's algorithm is based on Myhill-Nerode equivalence relation that splits the states into a group of equivalent classes. A set of … The following algorithms present various approaches to merging nondistinguishable states. Hopcroft's algorithm One 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. … See more In automata theory (a branch of theoretical computer science), DFA minimization is the task of transforming a given deterministic finite automaton (DFA) into an equivalent DFA that has a minimum number of states. … See more For each regular language, there also exists a minimal automaton that accepts it, that is, a DFA with a minimum number of states and this DFA … See more • State encoding for low power See more While the above procedures work for DFAs, the method of partitioning does not work for non-deterministic finite automata (NFAs). While an exhaustive search may minimize an NFA, … See more • DFA minimization using the Myhill–Nerode theorem See more
