WebStrong Induction vs. Weak Induction Think of strong induction as “my recursive call might be on LOTS of smaller values” (like mergesort–you cut your array in half) Think of weak induction as “my recursive call is always on one step smaller.” Practical advice: A strong hypothesis isn’t wrong when you only need a weak one (but a WebJun 30, 2024 · Strong induction and ordinary induction are used for exactly the same thing: proving that a predicate is true for all nonnegative integers.
