You'll get a detailed solution from a subject matter expert … 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.

WebProof: We will prove L = L (A) by showing two things: L (A) ⊆ L: We prove this by induction on the length of the string processed by A. Let the induction hypothesis be that for all strings of length n processed by A, if the accepting state is reached, then the string has an odd number of 1's. View the full answer Step 2/3 Step 3/3 Final answer WebDFA design, i.e., 8w2 :S(w). We will often prove such statements \by induction on the length of w".
