这种01背包的裸题,本来是不想写解题报告的.但是鉴于还没写过背包的解题报告.于是来一发. 这个真的是裸的01背包. 代码: #include <iostream> #include <cstdio> using namespace std; #define N 1007 int c[N],w[N],dp[N]; int main() { int t,i,n,V,v; scanf("%d",&t); while(t--) { scanf("%d%…

题意:给定一个体积,和一些物品的价值和体积,问你最大的价值. 析:最基础的01背包,dp[i] 表示体积 i 时最大价值. 代码如下: #pragma comment(linker, "/STACK:1024000000,1024000000") #include <cstdio> #include <string> #include <cstdlib> #include <cmath> #include <iostream>…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=2602 思路分析:该问题为经典的0-1背包问题:假设状态dp[i][v]表示前i件物品恰放入一个容量为v的背包可以获得的最大价值,则可以推导出dp递推公式 dp[i][v] = Max{dp[i-1][v], dp[i-1][v – c[i]] + w[i]}:c[i]表示第i件物品的容量,w[i]表示第i件物品的价值:该动态规划问题每个阶段的决策为是否要 选择第i件物品放入背包中,如果不选择第i件物…

意甲冠军:给出的数量和袋骨骼的数,然后给每块骨骼的价格值和音量.寻求袋最多可容纳骨骼价格值 难度;这个问题是最基本的01背包称号,不知道的话,推荐看<背包9说话> AC by SWS 主题链接 http://acm.hdu.edu.cn/showproblem.php?pid=2602 代码: #include<stdio.h> #include<string.h> typedef struct{ int w, v; }str; str s[1005]; int dp[…
