A Greedy Solution to the Knapsack Problem Earlier in thi pdf417 2d barcode for .NET s chapter we examined the knapsack problem and wrote a program to solve the problem using dynamic programming techniques. In this section we look at the problem again, this time looking for a greedy algorithm to solve the problem.

To use a greedy algorithm to solve the knapsack problem, the items we are placing in the knapsack need to be continuous in nature. In other words, they must be items like cloth or gold dust that cannot be counted discretely. If we are using these types of items, then we can simply divide the unit price by the unit volume to determine the value of the item.

An optimal solution is to place as much of the item with the highest value in the knapsack as possible until the item is depleted or the knapsack is full, followed by as much of the second highest value item as possible, and so on. The reason we can t nd.
