LESSON 13

LESSON 13. Overview of Previous Lesson(s). Over View. An NFA accepts a string if the symbols of the string specify a path from the start to an accepting state. These symbols may specify several paths, some of which lead to accepting state s and some that don't.

Deterministic Finite Automaton

Deterministic Finite Automaton. A deterministic finite automaton (DFA) is a five-tuple A = (Q, ?, ?, q 0, F) where Q is a finite set of states ? is a finite set of input symbols ? is a function ?: Q ? ?? Q called transition function q 0 ? Q is called the start state
