Greedy fractional knapsack problem

WebIf this is the integral knapsack problem, we would choose item #1 and #3, and this gives me total value 30. Of course, in fractional knapsack I can choose fractions of items. It turns out that the optimal solution is choose item #1 entirely and 0:8 fraction of item #2. The total weight is still 10, yet the value is now 32. WebDec 16, 2024 · Detailed solution for Fractional Knapsack Problem : Greedy Approach - Problem Statement: The weight of N items and their corresponding values are given. We have to put these items in a knapsack of weight W such that the total value obtained is maximized. Note: We can either take the item as a whole or break it into smaller units. …
