WebIn this tutorial we will learn about fractional knapsack problem, a greedy algorithm. In this problem the objective is to fill the knapsack with items to get maximum benefit (value or profit) without crossing the weight capacity of the knapsack. And we are also allowed to take an item in fractional part. Points to remember The knapsack problem is the following problem in combinatorial optimization: Given a set of items, each with a weight and a value, determine which items to include in the collection so that the total weight is less than or equal to a given limit and the total value is as large as possible.
