WebAlso in DFA null (or ε) move is not allowed, DFA can not change state without any input character. Non-deterministic Finite Automata ( NFA ) Non-deterministic finite automata - a state machine that can have states with multiple transitions for the same input symbol, and that can make “epsilon” moves, for no input at all. WebA DFA represents a finite state machine that recognizes a RE. For example, the following DFA: recognizes ( abc+) +.
