Dfa proof by induction length of x mod
Webthe induction proof works without strengthening here is a very special case, and does not hold in general for DFAs. Example II q 0 q 1 q 3 q 2 1 1 1 1 ... 2 Proving DFA Lower … WebThe proof of correctness of the machine is similar to the reasoning we used when building it. Simply setting up the induction proof forces us to write specifications and check all of the transitions. Claim: With M and L as above, L ( M) = L. We'll start the proof, get stuck, and then fix the proof.

Base Case: (even; ) = even and contains an even number of a’s (zero is even). Hence, state invariance holds for s= .
