DFA can only have one initial state, but can have zero, one or more than one final states over any number of input alphabet. When do you move from NFA to DFA? In DFA, on input 0 from state [A, B], we can move to state [A, B, C]. This step follows for all states of DFA.

WebAs it has a finite number of states, the machine is called Deterministic Finite Machine or Deterministic Finite Automaton. Formal Definition of a DFA A DFA can be represented by a 5-tuple (Q, ∑, δ, q 0, F) where − Q is a finite set of states. ∑ is a finite set of symbols called the alphabet. δ is the transition function where δ: Q × ∑ → Q WebJan 2, 2014 · A DFA only has one initial state, so you're probably making a mistake there.
