A DFA is presented in Figure 2-4 and an NFA for it in Figures 2-5 and 2.6. You can see how much more simple and intuitive the NFAs are. Example 3 As a final addition to our NFA's structure we consider this example: (ab)*∪(aba)*. This is, of course, different than the former example (ab∪. Solution. Step 1 −. Here the ε transition is between q1 and q2, so let q1 is X and qf is Y. Here the outgoing edges from q f is to q f for inputs 0 and 1. Step 2 −. Now we will Copy all these edges from q 1 without changing the edges from q f and get the following FA −. Step 3 −.
