Web@mAhMoUdDaFeR My point is it's possible to formally define NFAs in such a way that multiple initial states are admissible, but it's probably not possible to do so for DFAs in … WebJan 20, 2024 · The DFA’s start state is the set of all possible starting states in the NFA. This set is called the “epsilon closure” of the NFA’s start state. The epsilon closure is the set of all states that can be reached from the …
WebAs long as the final state belongs to one of the state in the set of Q (set of all possible states) , any number of final states are possible. A DFA can have only one start state … WebA DFA has to have at least two states, its start and an accept state. False L is a regular language if it could be described as a non-deterministic finite automaton (NFA). True By definition, the set of accept states F can NOT consist of all states Q. False Which of the following are true? ε + = ε , ε ∗ = ε, ∅ ∗ = { ε }
WebDesired Properties of State Invariants When you design a DFA, you need to design the state invariant for each state you want to have in the DFA. These state invariants must satisfy the following: No string should satisfy more than one invariant e.g., if one state claims that w has at least two 0’s, and another state WebApr 10, 2024 · My mom grabbed me and held me.
