       题目大意:有n件物品,每件物品均有各自的价值和体积,给你一个容量为 V 的背包,问这个背包最多能装的物品的价值是多少?        解题思路:这是一道0 - 1 背包的简单模板题,也是基础的DP问题,状态转移方程                       f[i][j] = max{ f[ i - 1 ][j] , f[ i - 1 ][ j - v[i] ] + w[i]  }         边界条件:f[0][0] = f[0][1] = ……  = f[0][ V ]…

题意:给出包裹的大小v,然后给出n块骨头的价值value和体积volume,求出一路下来包裹可以携带骨头最大价值 思路:01背包 1.二维数组(不常用 #include<iostream> #include<stdio.h> #include<math.h> using namespace std; ][]; int main() { int i,j; int t,n,_v;//测试用例个数,物品种类,背包大小 ],v[];//花费,价值 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>…
题意:01背包:有N件物品和一个容量为V的背包.每种物品均只有一件.第i件物品的费用是volume[i],价值是value[i],求解将哪些物品装入背包可使价值总和最大. 分析: 1.构造二维数组: dp[i][j]---前i件物品放入一个容量为j的背包可以获得的最大价值. dp[i][j] = max(dp[i - 1][j], dp[i - 1][j - volume[i]] + value[i]);---(a) (1)dp[i - 1][j]---不放第i件物品,因此前i件物品放入一个容量…
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%…
题目链接:https://vjudge.net/contest/103424#problem/A 题目大意: 第一行输入几组数据,第二行第一个数字代表物体个数,第二个数代表总体积.需要注意的是,第三排输入的是物品的价值,第四排的物品的体积.在不可以拆分物体的前提下,已知背包的总体积,最大能获取的价值是多少. 01背包模板题,没什么好说的.(附两种形式的dp数组解决方案) //一维dp数组实现(滚动数组) #include <iostream> #include <cstdio> #…
题意:收藏骨头. 思路: 常规的01背包. #include <iostream> #define N 1005 using namespace std; int volume[N]; //体积 int value[N]; //价值 int dp[N]; //总价值(动态更新) int max(int a,int b) { return a>b?a:b; } void cal(int n,int v) //不断更新数组dp { int i,j; ;i<=n;i++) ;j--) d…

这题和典型的01背包求最优解不同,是要求第k优解,所以,最直观的想法就是在01背包的基础上再增加一维表示第k大时的价值.具体思路见下面的参考链接,说的很详细 参考连接:http://laiba2004.blog.163.com/blog/static/8835120220138611342496/http://hi.baidu.com/chenyun00/item/1c6c44318acc8bfaa88428c7 #include <iostream> #include <cstdio&…
