WebStructural Induction. In many situations, in order to prove programs equivalent, we will need to do a proof over infinite sets of structures — all natural numbers, lists, or trees. Establishing properties over inifinite sets is challenging because simple proof techniques such as exhaustive case analysis are often not powerful enough. WebProof By Cases •New code structure means new proof structure •Can split a proof into cases –e.g., d = Fand d = B –e.g., n ≥ 0and n < 0 –need to be sure the cases are exhaustive •Structural induction and Proof By Cases are related –one case per constructor –structural induction adds the inductive hypothesis part

Recursive Definitions and Structural Induction

WebIStuctural inductionis a technique that allows us to apply induction on recursive de nitions even if there is no integer. IStructural induction is also no more powerful than regular … WebIn general, any element of an inductively defined set is built up by applying the rules defining the set, so if you provide a proof for each rule, you have given a proof for every element. … WebInduction and Recursion. 6.8. Structural Induction. So far we’ve proved the correctness of recursive functions on natural numbers. We can do correctness proofs about recursive functions on variant types, too. That requires us to figure out how induction works on variants. We’ll do that, next, starting with a variant type for representing ... health hustle fitness
