WebThe Knapsack ProblemThe Knapsack Problem There are two versions of the problem: 1. “Fractional” knapsack problem. 2. “0/1” knapsack problem. 1 Items are divisible: you can take any fraction of an item. Solved with a greedy algorithm. 2 Item are indivisible; you either take an item or not. Solved with dynamic programming. WebThe Greedy algorithm could be understood very well with a well-known problem referred to as Knapsack problem. Although the same problem could be solved by employing other algorithmic approaches, Greedy approach solves Fractional Knapsack problem reasonably in a good time.
