Can we have more than one Deterministic Finite Automata diagrams for a set of strings?
Can we have more than one Deterministic Finite Automata (DFA) diagrams for a set of strings?


Of course!

There's also an algorithm to minimize a deterministic finite automata into a minimal deterministic finite automata. The existence of such algorithm is a proof that for most, if not all, sets of strings, many DFAs can be defined.
