WebI know a DFA can have multiple accepting states, but can an NFA also have multiple accepting states? finite-automata Share Cite Follow asked Dec 28, 2016 at 10:49 user63810 21 1 2 Add a comment 1 Answer Sorted by: 6 Whenever one is in doubt about central notions, one must consult the definitions of them. Web11 aug. 2016 · Your proposed solution can easily be transformed into a DFA with a singular initial state: Add a state q 0 ~, add transitions δ ( q 0 ~, q) = q (ok, I'm abusing notation here - your alphabet needs an element to represent each of your states in this case, but you could also encode them as words of whatever elements your alphabet has) to δ and …

DFA Deterministic Finite Automata - Javatpoint

WebDFA can contain multiple final states. It is used in Lexical Analysis in Compiler. In the following diagram, we can see that from state q0 for input a, there is only one path which is going to q1. Similarly, from q0, there is … WebA DFA is universal if and only if all states are final states, but this does not hold for NFAs. The Equality, Inclusion and Minimization Problems are also PSPACE complete since … darwin moving calgary

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. Web30 jan. 2014 · 2. I'm having trouble understanding how to estimate the number of states in the intersection of two DFA's (M1 and M2, which have n and k states). I don't want to construct an actual DFA, but to understand how many states an intersection will give. For example, the union of M1 and M2 will give n x k states (if I have understood this … Web4 feb. 2012 · For instance, a minimal DFA for the language {a} over alphabet {a, b} must have 3 states: a start state where you can see a and accept; an accepting state where you reject if you see anything else; and a dead state where you go if you see a b or anything in the accepting state. Never heard of omitting dead states from minimal DFAs. … darwin movers calgary
