Strong induction (CS 2800, Spring 2024) - Cornell University

WebStrong induction works on the same principle as weak induction, but is generally easier to prove theorems with. Example: Prove that every integer n greater than or equal to 2 can be factored into prime numbers. Proof: We proceed by (strong) induction. Base case: If n = 2, then n is a prime number, and its factorization is itself. shut down pc safely

WebA stronger statement (sometimes called “strong induction”) that is sometimes easier to work with is this: Let S(n) be any statement about a natural number n. To show using strong induction that S(n) is true for all n ≥ 0 we must do this: If we assume that S(m) is true for all 0 ≤ m < k then we can show that S(k) is also true. WebJan 17, 2024 · Steps for proof by induction: The Basis Step. The Hypothesis Step. And The Inductive Step. Where our basis step is to validate our statement by proving it is true when n equals 1. Then we assume the statement is correct for n = k, and we want to show that it is also proper for when n = k+1.

WebSep 5, 2024 · The strong form of mathematical induction (a.k.a. the principle of complete induction, PCI; also a.k.a. course-of-values induction) is so-called because the hypotheses one uses are stronger. Instead of showing that P k P k + 1 in the inductive step, we get to assume that all the statements numbered smaller than P k + 1 are true. WebProofs by Induction A proof by induction is just like an ordinary proof in which every step must be justified. However it employs a neat trick which allows you to prove a statement …
