Knapsack fraction problem
WebThe capacity of the Knapsack is W. As the name suggests, in the Knapsack problem, items can be broken into smaller fragments. So, the thief might only take a fraction or a part of xi of ith item. 0⩽xi⩽1. The ith item in the store contributes a weight of xi.wi to the total weight in the knapsack (bag) and profit xi.pi to the Total Profit. WebKnapsack Problem- You are given the following- A knapsack (kind of shoulder bag) with limited weight capacity. Few items each having some weight and value. The problem states- Which items should be placed into the knapsack such that- The value or profit obtained by putting the items into the knapsack is maximum.
