Greedy knapsack
WebOct 9, 2024 · Give a greedy algorithm to find an optimal solution to this variant of the knapsack problem. Prove the correctness and running time. So the greedy algorithm I came up with was to sort the items based off of increasing weight which is also decreasing value. This means that the price per weight is in decreasing order.
