WebAug 1, 2024 · Proof of strong induction from weak: Assume that for some , the statement is true and for every . Let be the set of all for which is false. If and so by well-ordering, has a least element, say . By the definition of , for every is true. The premise of the inductive hypothesis is true, and so is true, contradicting that . Hence .
WebIt is easy to see that if strong induction is true then simple induction is true: if you know that statement p ( i) is true for all i less than or equal to k, then you know that it is true, in particular, for i = k and can use simple induction. It is harder to prove, but still true, that if strong induction is true, then simple induction is true. WebI Hence, structural induction is just strong induction, but you don't have to make this argument in every proof!

WebInduction setup variation Here are several variations. First, we might phrase the inductive setup as ‘strong induction’. The di erence from the last proof is in bold. Proof. We will prove this by inducting on n. Base case: Observe that 3 divides 50 1 = 0. Inductive step: Assume that the theorem holds for n k, where k 0. We will prove that ...
WebInduction Gone Awry • Definition: If a!= b are two positive integers, define max(a, b) as the larger of a or b.If a = b define max(a, b) = a = b. • Conjecture A(n): if a and b are two positive integers such that max(a, b) = n, then a = b. • Proof (by induction): Base Case: A(1) is true, since if max(a, b) = 1, then both a and b are at most 1.Only a = b = 1 satisfies this condition. northernchateau web camWebStrong Induction is another form of mathematical induction.
