sum+=(double)sinp[i]*wi[i]; //如果上面总价（vi）也交换的话，这可以写为sum+=vi[i];c-=wi[i];} else { sum+=(double)sinp[i]*c;break; //容量满了，退出 } } printf("%.1lf\n",sum);}
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。
Knapsack problem is also called as rucksack problem. In Knapsack problem, given a set items with values and weights and a limited weight bag . We have to find the optimum solution so that, in minimum cost(value) fill the bag with the maximum weight. C Pr
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....
The mKPC is NP-complete because it contains the min-Knapsack problem as a special case when Δ=n. In the applications described in Section 1.1, however, it can often be the case that all items take unit cost (i.e., cj=1 for all i∈{1,…,n}). This problem is denoted as 1c-...
在这个压缩包"0-1-knapsack-problem-master (249)c.zip"中,我们可以推测它包含了一个用C语言实现的0-1背包问题的解决方案。 0-1 背包问题的基本设定如下:有一组物品,每个物品有重量和价值,还有一个最大承重的背包。目标是在不超过背包最大承重的前提下,选择物品以使总价值最大化。每个物品只能选择0个或1个...
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 ...
Hi guys! In this article, I am trying to explain the knapsack problem in the Analysis and design of algorithms. This article is really helpful for the students. A thief robbing a store that can carry a maximal weight of 'w' into his knapsack. There are 'n' no of items in store avai...
在给定的压缩包 "0-1-knapsack-problem-master (242)c.zip" 中,我们可以推测包含的是一个用C语言实现的0-1背包问题的代码示例。C语言是一种基础且高效的编程语言,适合用于解释和演示算法的底层逻辑。 0-1 背包问题的基本设定是:有一个背包,其容量为W,有一组物品,第i个物品的重量为w[i],价值为v[i],并...
