针对三件物品,我们可以采用穷举法罗列所有可能的选项,如果物品件数较多,假设有10件物品,就需要罗列1024次才可能求出最终的解;假定有N件物品,如果采用穷举法,我们需要进行2^N 罗列才能求出解,显然这样效率很低,在N较大时候,程序运行效率很低,甚至无法求解。 按照《算法导论》的模板,仍然采用CRCC模式对此问题进行分析。

This chapter discusses the well-known knapsack problem. This problem is another classical problem and is quoted as often in the problem-solving literature as the traveling salesman problem of Chapter 6. According to the problem classification of the model theory approach, the knapsack problem is ...
01背包问题(01knapsackproblem)0 / 1 背包问题(0 / 1 knapsack problem)背包问题(Knapsack problem)是⼀种组合优化的问题。问题可以描述为:给定⼀组物品,每种物品都有⾃⼰的重量和价格,在限定的总重量内,我们如何选择,才能使得物品的总价格最⾼。问题的名称来源于如何选择最合适的物品放置于给定背包...
Given N objects, where the j th object owns its weight wj and profit pj, and a knapsack that can hold a limited weight capability C, the goal of this problem is to pack the knapsack so that the objects in it have the maximal value among all possible ways the knapsack can be packed....
knapsack problem Knapsack Problems I.History 1.1Introduction Knapsack Problems have been intensively studied since the pioneering work of Dantzig in the late 50’s, both because of their immediate applications in industry and financial management, but more pronounced for theoretical reasons, as Knapsack...
Motivated by this scenario, we introduce the complex-demand knapsack problem (C-KP), a new variation of the traditional knapsack problem, where each item is associated with a demand as a complex number, rather than a real number often interpreted as weight or size of the item. While keeping...
C Gomes,Joo Clímaco,J Figueira 被引量: 6发表: 2005年 Some Complexity Issues In A Class Of Knapsack Problems: What Makes A Knapsack Problem "Hard"? We propose a new class of knapsack problems by assiuning that the sizes of the items to be put into a knapsack are known to be elements...

Then S = S {i} is an optimal solution for W wi dollars and the value to the solution S is Vi plus the value of the sub-problem.We can express this fact in the following formula: define c[i, w] to be the solution for items 1,2, , i and the maximum weight w....
