Simple induction proofs
WebbProof by strong induction Step 1. Demonstrate the base case: This is where you verify that P (k_0) P (k0) is true. In most cases, k_0=1. k0 = 1. Step 2. Prove the inductive step: This is where you assume that all of P (k_0) P (k0), P (k_0+1), P (k_0+2), \ldots, P (k) P (k0 +1),P (k0 +2),…,P (k) are true (our inductive hypothesis).

WebbIn this paper, we investigate the potential of the Boyer-Moore waterfall model for the automation of inductive proofs within a modern proof assistant. We analyze the basic concepts and methodology underlying this 30-year-old model and implement a new, fully integrated tool in the theorem prover HOL Light that can be invoked as a tactic. We also … http://www.cs.hunter.cuny.edu/~saad/courses/dm/notes/note5.pdf
Webb3 / 7 Directionality in Induction In the inductive step of a proof, you need to prove this statement: If P(k) is true, then P(k+1) is true. Typically, in an inductive proof, you'd start off by assuming that P(k) was true, then would proceed to show that P(k+1) must also be true. In practice, it can be easy to inadvertently get this backwards.

The way we do step 2 is assume it's true for some arbitrary value (in this case k). how fix volumeWebbIn Coq, the steps are the same: we begin with the goal of proving P(n) for all n and break it down (by applying the induction tactic) into two separate subgoals: one where we must show P(O) and another where we must show P(n') → P(S n'). Here's how this works for the theorem at hand: Theorem plus_n_O : ∀n: nat, n = n + 0.

Step 3 (Induction Step) Remember that our goal for this step is to prove the following statement: ∀ i ∈ N, P (i) ⇒ P (i + 1). If you remember the proof structures from CSC165, you’ll know that the first step is to let i be a natural number, and assume that P (i) is true. highest 7th wicket partnership in testWebbWith these two facts in hand, the induction principle says that the predicate P(n) is true for all natural n. And so the theorem is proved! A Template for Induction Proofs The proof of Theorem 2 was relatively simple, but even the most complicated induction proof follows exactly the same template.
