WebThe fractional knapsack problem is also one of the techniques which are used to solve the knapsack problem. In fractional knapsack, the items are broken in order to maximize the profit. The problem in which we break the item is known as a Fractional knapsack problem. This problem can be solved with the help of using two techniques: WebEx: ( Fractional knapsack) c=20 weights = [18,15,10] values = [25,24,15] The maximum profit that can be obtained is 31.5 (By considering the second item and half of third item) Solution vector= [0,1,1/2] 2) Naive Approach This approach involves trying all possible subsets of items and fractions and keeps track of the maximum profit obtained.
