Can a dfa have multiple start states
WebCompared to deterministic FA, you can have more than one transition function with the same character starting from a single state and you can have "empty" transitions, and you can "choose" which one to follow … 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.
