这里;http://acm.hdu.edu.cn/showproblem.php?pid=1059 题意是有价值分别为1,2,3,4,5,6的商品各若干个,给出每种商品的数量,问是否能够分成价值相等的两份. 联想到多重背包,稍微用二进制优化一下.(最近身体不适,压力山大啊) #include<iostream> #include<cstring> #include<cstdio> #define inf 70000 using namespace std; int dp…

Dividing Sample Input 1 0 1 2 0 0 价值为1,2,3,4,5,6的物品数目分别为 1 0 1 2 0 0,求能否将这些物品按价值分为两堆,转化为多重背包.1 0 0 0 1 10 0 0 0 0 0   Sample Output   Collection #1: Can't be divided.   Collection #2: Can be divided. #include <algorithm> #include <iostream> #i…

题意:价值分别为1,2,3,4,5,6的物品个数分别为a[1],a[2],a[3],a[4],a[5],a[6],问能不能分成两堆价值相等的. 解法:转化成多重背包 #include<stdio.h> #include<string.h> #include<algorithm> #include<iostream> using namespace std; ]; ]; int nValue; //0-1背包,代价为cost,获得的价值为weight void…

思路: 这个方法要看<浅谈几类背包问题>这篇论文. #include"stdio.h" #define Max(a,b) (a)>(b)?(a):(b) ],k[]; int main() { ; ],&k[],&k[],&k[],&k[],&k[])!=EOF,k[]|k[]|k[]|k[]|k[]|k[]) { ;i<=;i++) f[i]=; ]+k[]*+k[]*+k[]*+k[]*+k[]*; sum%=; ;…
