Strong vs weak induction

WebMay 27, 2024 · Reverse induction is a method of using an inductive step that uses a negative in the inductive step. It is a minor variant of weak induction. The process still applies only to countable sets, generally the set of whole numbers or integers, and will frequently stop at 1 or 0, rather than working for all positive numbers. WebFeb 19, 2024 · The difference between strong induction and weak induction is only the set of assumptions made in the inductive step. The intuition for why strong induction works is the same reason as that for weak induction : in order to prove [math]P(5) [/math] , for example, I would first use the base case to conclude [math]P(0) [/math] .
