WebMay 28, 2009 · Abstract. We show that the absolute worst case time complexity for Hopcroft’s minimization algorithm applied to unary languages is reached only for deterministic automata or cover automata following the structure of the de Bruijn words. A previous paper by Berstel and Carton gave the example of de Bruijn words as a … 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
WebJun 21, 2012 · To understand this look at this DFA (drawn by JFLAP ): Minimization would combine q1 and q2, but the outlined algorithm does not manage to.

All is good, let's generate the DFA for the second regex now. After applying Hopcroft's algorithm, it occurs to me that the result is the same. However, the minimization of the second DFA is incorrect because it also allows to repeat the letter b indefinitely ...
WebThe initial state of the minimum DFA is the one containing the initial state of the input DFA, and the accepting states of the minimum DFA are the ones whose members are accepting states of the input DFA. Moore's algorithm. Moore's algorithm for DFA minimization is due to Edward F. Moore . Like Hopcroft's algorithm, it maintains a partition ... WebVer histórico. Em ciência da computação, mais especificamente no ramo da teoria dos autômatos, Minimização de AFD é o processo de transformação de um dado autômato finito determinístico (AFD) em outro equivalente que tenha um número mínimo de estados. Aqui, dois AFDs são ditos equivalentes se eles descrevem a mesma linguagem regular.
