WebTo put it in terms of induction, a one inch rod can be cut in 1 = 2 1 − 1 way (not at all). If a length k rod can be cut in 2 k − 1 ways, a length k + 1 rod can be cut either by cutting off the right inch and cut the remaining in 2 k − 1 ways or by not cutting off the right inch and cut the remaining in 2 k − 1 ways, totaling 2 ( k + 1) − 1 ways. WebProof: We proceed here by induction. The cases n ∈ { 0, 1 } should be clear. So lets assume the induction hypothesis holds for n ′ with 0 ≤ n ′ < n. Lets compute T ( n) using the induction hypothesis in the second equality: T ( n) = T ( n − 1) + T ( n − 2) + 1 = ( 2 F n − 1) + ( 2 F n − 1 − 1) + 1 = 2 ( F n + F n − 1) − 1 = 2 F n + 1 − 1.

Base case: every input array of length 1 is already sorted (P (1) holds) Inductive step: fix n => 2. Fix some input array of length n. Need to show: if P (k) holds for all k < n, then P (n) holds as well.

Web3. It is useful to think of induction proofs as an "outline" for an infinite length proof. In particular, what you a providing is a way to write a proof for any particular n. For example, say you've proven 1 + 2 +... + n = n ( n + 1) / 2 by induction. We can think of this as giving me a 'program' to write a proof for, say, n = 6 or n = 100000 ... Web• Prove the Recurrence is Correct. Having written out your recurrence, you will need to prove it is correct. Typically, you would do so by going case-by-case and proving that each case is correct. In doing so, you will often use a “cut-and-paste” argument to show why the cases are correct. • Prove the Algorithm Evaluates the Recurrence.
