WebDec 13, 2016 · You can construct such DFA by using Thompson or Glushkov construction (among others) to construct an NFA, and then convert it to a DFA. If a language is produced by a DFA, it is regular, and can be described by a regular expression. To construct a regular expression from a DFA, have a look at this question. WebThe following DFA is a lexical analyzer which is supposed to recognize comments. The lexical analyzer will ignore the comment and goes back to the state one. I'm told that there's something wrong with it but I can't …

Final answer. Step 1/2. I understand your request, and I will provide a deterministic finite automaton (DFA) for the given language. Language: {w ∈ {a, b}* odd-length w begins with 'a', even-length w ends with 'b'} To design a DFA for this language, we'll have four states: q0, q1, q2, and q3. View the full answer.

The classic example of a simply described language that no DFA can recognize is bracket or Dyck language, i.e., the language that consists of properly paired brackets such as word "(()())". Intuitively, no DFA can recognize the Dyck language because DFAs are not ... WebJan 23, 2015 · Given a complete DFA ( Q, A, δ, i, F) accepting the regular language L, the DFA ( Q, A, δ, i, Q − F) accepts the complement of L. This is still perfectly true if F = Q, in which case Q − F is empty. In other words, if you were assuming that the set of final states is nonempty, the previous proof would not work in all cases, which would be ...
