Can a dfa have no accept states
WebA language is 0-reversible if the reversal of the minimal DFA for the language is also deterministic. The reversing operation is defined as swapping initial and final states, and inverting the edge relation of the DFA. This means that a 0-reversible language can have only one accepting state. WebA language is 0-reversible if the reversal of the minimal DFA for the language is also deterministic. The reversing operation is defined as swapping initial and final states, and …

This can always be done by constructing a GNFA with two extra states, the new start and accept states of the GNFA and properly modifying the transitions in the GNFA. In particular we take the original DFA and add a start state and an accept state. From this new start state we add arrows to all other states. All of these new ...

Thus, the DFA will have a unique path to the final state after processing the entire input string. If final state is an …
WebThis DFA does not accept any string because it has no accepting state. Thus the language it accepts is the empty set . Example 3 : DFA with one cycle This DFA has a cycle: 1 - 2 - 1 and it can go through this cycle any number of times by reading substring ab repeatedly. To find the language it accepts, first from the initial state go to state 1 ... WebJan 22, 2024 · As you have already observed, to accept the empty string, the initial state must also be a final/accepting state. Is there possible zero number of final state in DFA? DFA can only have one initial state, but can have zero, one or more than one final states over any number of input alphabet. Can a DFA have zero accept states? A DFA is …
