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. WebGreedy We can solve the fractional knapsack problem with a greedy algorithm: 1. Compute the value per pound (vi/wi) for each item 2. Sort the items by value per pound 3. The thief then follows the greedy strategy of always taking as much as possible of the item remaining which has highest value per pound. 20
