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 is a C++ Program to knapsack problem using dynamic programming. The knapsack problem or rucksack problem is a problem in combinatorial optimization: Given a set of items, each with a mass and a value, determine the number of each item to include in a collection so that the total weight...
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...
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 ...
