Draw the state diagram of the NFA that … WebJan 23, 2015 · There is no requirement that the set of accepting states be non-empty. A DFA must always have an initial state, so the minimum number of states needed to accept the empty language is one. – user208259 Jan 23, 2015 at 7:51 Thank you, Definition of DFA does not require the set of final states to be non empty.
WebA DFA can have multiple start states. False. A DFA may have zero accept states. True. If a finite automaton accepts no string, it recognizes only the empty string. False. The alphabet of a DFA must have cardinality at least 1. True. Given a … 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 …
WebJan 2, 2014 · To construct the DFA D that accepts the complement of L, simply convert each accepting state in A into a non-accepting state in D and convert each non-accepting state in A into an accept state in D. ( Warning! This is not true for NFA's) A is DFA of L, D is for complement WebDFA with an accepting state in the initial state. F is the set of final states: F = { q 0, q 2 }. δ ( q 0, 0) = q 1 δ ( q 0, 1) = q 2 δ ( q 1, 0) = q 1 δ ( q 1, 1) = q 1 δ ( q 2, 0) = q 2 δ ( q 2, 1) …
Webinto a GNFA. 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 … onslow st south perththe DFA with a minimum number of states for a particular regular language (Minimization Problem) DFAs are equivalent in computing power to nondeterministic finite automata (NFAs). This is because, firstly any DFA is also an NFA, so an NFA can do what a DFA can do.
