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 ...

The knapsack problem asks to choose a subset of the items such that their overall profit is maximized, while the overall weight does not exceed a given capacity c. Introducing binary variables xj to indicate whether item j is included in the knapsack or not the model may be defined: $$ {...

in the knapsack. The problem solver only needs to decide whether to take the item or not based on the weight that can still be accepted. However, if it is a program, re-computation is not independent and would cause problems. This is where dynamic programming techniques can be applied. ...
