Web• When proving something by induction… – Often easier to prove a more general (harder) problem – Extra conditions makes things easier in inductive case • You have to prove more things in base case & inductive case • But you get to use the results in your inductive hypothesis • e.g., tiling for n x n boards is impossible, but 2n x ... Webof proving both mathematical statements over sequences of integers, as well as statements about the complexity and correctness of recursive algorithms. The goal of mathematical induction is to prove that some statement, or proposition P(n)is true for all integers n≥afor some constant a. For example, we may want to prove that: Xn i=1 i= n( +1) 2

We prove that a given hypothesis is true for the smallest possible value. Typical problem size is n = 0 or n = 1. Step 2: Induction hypothesis. In this step, we assume that the given hypothesis is true for n = k. Step 3: Inductive step. reshade lighting
how to prove the correctness of recursive algorithm?
Mathematical induction is a proof method often used to prove statements about integers. We’ll use the notation P(n), where n ≥ 0,to denote such a statement.To prove P(n) with induction is a two-step procedure. 1. Base case:Show that P(0) is true. 2. Inductive step: Show that P(k) is trueif P(i) is true for all … Meer weergeven Let’s start with a statement P(n) from mathematics. We’ll use induction to prove P(n)for all n≥ 1.(If we define the empty sum to be zero, P(0) is true as well.)
