Greedy fractional knapsack
WebKnapsack Problem . The knapsack problem is one of the famous and important problems that come under the greedy method. As this problem is solved using a greedy method, this problem is one of the optimization problems, more precisely a combinatorial optimization.. The optimization problem needs to find an optimal solution and hence no exhaustive … Web$ gcc knapsack-greedy-method.c $ ./a.out Enter the capacity of knapsack: 50 Enter the number of items: 3 Enter the weight and value of 3 item: Weight[0]: 10 Value[0]: 60 Weight[1]: 20 Value[1]: 100 Weight[2]: 30 Value[2]: 120 Added object 1 (60 Rs., 10Kg) completely in the bag.

WebOct 12, 2024 · A greedy algorithm based on value per weight would first choose item A and then quit, there being insufficient capacity left for any other item -- total value 1.65. The optimal solution, however, is to choose items B and C, which together exactly take up the full capacity and have a combined value of 2.
