题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=2602 解题思路:给出一个容量为V的包,以及n个物品,每一个物品的耗费的费用记作c[i](即该物品的体积),每一个物品的价值记作w[i], 我们用 f[v]来表示一个容量为v的包的总价值,这样最后我们只需要输出f[V]就能得出结果 则对于第i个物品,它可以放入背包,此时背包的容量变为v-c[i],背包的总价值变为f[v-c[i]]+w[i], 它也可以不放入背包,此时背包的容量还是v,背包的总价值不变…

解题思路:对于01背包的状态转移方程式f[v]=max(f[v],f[v-c[i]+w[i]]);其实01背包记录了每一个装法的背包值,但是在01背包中我们通常求的是最优解, 即为取的是f[v],f[v-c[i]]+w[i]中的最大值,但是现在要求第k大的值,我们就分别用两个数组保留f[v]的前k个值,f[v-c[i]]+w[i]的前k个值,再将这两个数组合并,取第k名. 即f的数组会增加一维. http://blog.csdn.net/lulipeng_cpp/article/details/…
