Dfa for string containing ab
WebApr 13, 2024 · Here are the steps for constructing the NFA algorithmically: Let's first construct the regular expression corresponding to the language L, simplest regular expression for L is ( ( a + b) ∗ a a ( a + b) ∗ b b ( a + b) ∗) + ( ( ( a + b) ∗ b b ( a + b) ∗ a a ( a + b) ∗). Now use the construction algorithm to convert a regular ... WebThe DFA accepts w if the path ends in a final state. Otherwise the DFA rejects w. The language of a DFA is the set of accepted strings. Example. The example DFA accepts the strings a, b, ab, bb, abb, bbb, …, abn, bbn, …. So the language of the DFA is given by the regular expression (a + b)b*. Start 0 1 2 a b a b a b Start 0 1 2 a, b a b a, b

WebJun 11, 2024 · Design a DFA which accepts a language over the alphabets Σ = {a, b} such that L is the set of all strings starting with ‘aba’. All strings start with the substring “aba”. Therefore, length of substring = 3. Minimum number of states in the DFA = 3 + 2 = 5. The language L= {aba,abaa,abaab,abaaba} The transition diagram is as follows −. WebRegular expression for the given language = ab(a + b)* Step-01: All strings of the language starts with substring “ab”. So, length of substring = 2. Thus, Minimum number of states required in the DFA = 2 + 2 = 4. It suggests that minimized DFA will have 4 states. Step-02: We will construct DFA for the following strings-ab; aba; abab Step-03:

Visit Stack Exchange WebDec 2, 2024 · Designing step-by-step : Step-1: Take a initial state A,and smallest possible string are ab and ba, if A takes ‘a’ as first input alphabet it goes to state B and if A takes ‘b’ as first input alphabet it goes to state C. Step-2: Now think about state B, if it takes input alphabet ‘a’,it breaks our condition of only one ‘a’ but ...
WebIn particular, the start state of the DFA is the ε-closure of the NFA start state, i.e., s′ = Ε(s) Final States Reviewing our idea that, for a given string w the relevant DFA state is the set of all NFA states reachable from the start state by w. Thus a final state of the DFA should be any state set which contains some final state of the ...
