How many final states can a dfa have
Web21 jun. 2015 · If the n -bit automaton has k states, then the corresponding finite-state automaton has 2 n k states. An automaton that stores m binary words each of length n has a total of mn bits of memory, so each state of the mn -bit automaton corresponds to 2 m n states of the corresponding memoryless finite-state automaton. Share Cite Follow Web2 okt. 2024 · Yes. That one state must be the initial state. If it is also an acceptor state, the DFA accepts the language $\{\epsilon\}$; if not, the DFA accepts the language $\varnothing$. Both of these are languages over any alphabet, including the empty alphabet.

WebSo a trap state can be final or non final, since both can have either no transitions defined or have transitions for every symbol happening to itself. A final state cannot be a dead state, as we can read ϵ and stay in the same state, which is final state. But this, seems incorrect, as epsilon moves are not allowed in DFAs.
