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 $P_k \implies P_{k+1}$ in the inductive step, we get to assume that all the statements numbered smaller than $P_{k+1}$ are true. Webis true. In Strong Induction, you assume P(k);P(k 1);P(k 2);:::;P(a) are all true. That is, you make a stronger assumption about the values of n which make P(n) true, hence the name Strong Induction. From this stronger assumption, you proceed as before to show that P(k + 1) is true. It may be shown that Regular Induction implies Strong ... mem.h in c

WebApr 4, 2024 · Some of the most surprising proofs by induction are the ones in which we induct on the integers in an unusual order: not just going 1, 2, 3, …. The classical example of this is the proof of the AM-GM inequality. We prove a + b 2 ≥ √ab as the base case, and use it to go from the n -variable case to the 2n -variable case. WebApr 17, 2024 · In a proof by mathematical induction, we “start with a first step” and then prove that we can always go from one step to the next step. We can use this same idea to define a sequence as well. We can think of a sequence as an infinite list of numbers that are indexed by the natural numbers (or some infinite subset of $\mathbb{N} \cup \{0\})$.

WebOn the other hand, any proof by strong induction can be trivially rephrased as a proof by "weak" induction. One reason for the terminological difficulty is that the only place that people talk about "strong induction" is in introductory courses. There, "use strong induction" can be a hint about what sort of induction hypothesis to choose.
