Difference Between DFA and NDFA Sr Parameter NFA FA 1 Transition Non deterministic Deterministic 2 Power NFA is as powerful as DFA FA is powerful as an NFA 3 Design Easy to design due to non-determinism More difficult to design 4 Acceptance It is difficult to find whether w ∈ L as there are several paths. Backtracking is required to explore several parallel paths. It is easy to find whether w ∈ L as transition are deterministic
