WebDeterministic Finite Automata (DFA) We now begin the machine view of processing a string over alphabet Σ. The machine has a semi-infinite tape of squares holding one alphabet symbol per square. The machine has a finite state set, K, with a known start state. Initially we want the processing to be deterministic, that is, there is only one ...

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 ... WebFor the rest, you should show that your DFA is minimal (it is). It appears that your NFA is correct, so if you convert that to a DFA and minimize it you should get your original DFA (though it would be tedious to do by hand). Don't worry about the fact that there different ways to do the NFA to DFA construction: either will work. $\endgroup$
