WebJul 27, 2024 · Construction of DFA that accepts strings that does not contain aababa 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. $\endgroup$
