Fractional knapsack proof by induction

WebDec 14, 2024 · 5. To prove this you would first check the base case n = 1. This is just a fairly straightforward calculation to do by hand. Then, you assume the formula works for n. This is your "inductive hypothesis". So we have. ∑ k = 1 n 1 k ( k + 1) = n n + 1. Now we can add 1 ( n + 1) ( n + 2) to both sides: WebGreedy Knapsack Proof Preview Greedy choice property: – We need to show that our first greedy choice g 1 is included in some optimal solution O.
