Web摘要：. The discounted {0–1} knapsack problem (DKP) is an extension of the classical {0–1} knapsack problem (KP) that consists of selecting a set of item groups where each group includes three items and at most one of the three items can be selected. The DKP is more challenging than the KP because four choices of items in an item group ...
