WebJan 10, 2024 · Induction is powerful! Think how much easier it is to knock over dominoes when you don't have to push over each domino yourself. You just start the chain reaction, and the rely on the relative nearness of the dominoes to take care of the rest. Think about our study of sequences. Web(d) Conclude that 8n 2Z.P(n) by strong induction (i.e. by the statements proven in steps 3 and 4 and the strong induction principle). We now consider the fundamental theorem of arithmetic. Theorem 3. Every non-prime positive integer greater than one can be written as the product of prime numbers. Proof. We proceed by strong induction.
WebStrong induction is often found in proofs of results for objects that are defined inductively. An inductive definition (or recursive definition) defines the elements in a sequence in terms of earlier elements in the sequence. It usually involves specifying one or more base cases and one or more rules for obtaining “later” cases. WebStrong induction is good when you are shrinking the problem, but you can't be sure by how much. Splitting a set into two smaller sets Taking the remainder of one number divided by another Weak Induction is a consequence of the Well Order Principle and a special case of Structural Induction as you mentioned before.
WebInductive Step : Prove the next step based on the induction hypothesis. (i. Show that Induction hypothesis P(k) implies P(k+1)) Weak Induction, Strong Induction. This part was not covered in the lecture explicitly. However, it is always a good idea to keep this in mind regarding the differences between weak induction and strong induction. WebProof by Strong Induction State that you are attempting to prove something by strong induction. State what your choice of P(n) is. Prove the base case: State what P(0) is, then prove it. Prove the inductive step: State that you assume for all 0 ≤ n' ≤ n, that P(n') is true. State what P(n + 1) is.
