WebbPrintable version. Strong induction is a type of proof closely related to simple induction. As in simple induction, we have a statement P(n) P ( n) about the whole number n n, and we want to prove that P(n) P ( n) is true for every value of n n. To prove this using strong induction, we do the following: The base case. WebbMathematical induction plays a prominent role in the analysis of algorithms. There are various reasons for this, but in our setting we in particular use mathematical induction to prove the correctness of recursive algorithms.In this setting, commonly a simple induction is not sufficient, and we need to use strong induction.. We will, nonetheless, use simple …

Assume P(n): an integer n can be written as a product of primes. … WebbThe recipe for strong induction is as follows: State the proposition P(n) that you are trying to prove to be true for all n. Base case:Prove that the proposition holds for n = 0, i.e., prove that P(0) is true. Inductive step:Assuming the induction hypothesis that P(n) holds for all n between 0 and k, prove that P(k+1) is true.
