Abstract

A regular language is generally accepted by a single finite automaton. An approach of dual finite automata is presented here. An input string is scanned by two deterministic finite automata 1992: reading from the string's head and tail respectively. One of them accepts the regular language itself; the other accepts the language's reversal. Whether a string is accepted depends on the states of both automata, when their reading heads meet. Dual finite automata can be applied in compiler generation and parallel computing.
