滑雪 Time Limit: 1000MS   Memory Limit: 65536K Total Submissions: 67987   Accepted: 25013 Description Michael喜欢滑雪百这并不奇怪, 因为滑雪的确很刺激.可是为了获得速度,滑的区域必须向下倾斜,而且当你滑到坡底,你不得不再次走上坡或者等待升降机来载你.Michael想知道载一个区域中最长底滑坡.区域由一个二维数组给出.数组的每个数字代表点的高度.下面是一个例子 1 2 3 4 5 16 17

一.问题描述 物品无限的背包问题:有n种物品,每种均有无穷多个.第 i 种物品的体积为Vi,重量为Wi.选一些物品装到一个容量为 C 的背包中,求使得背包内物品总体积不超过C的前提下重量的最大值.1≤n≤100, 1≤Vi≤C≤10000, 1≤Wi≤1000000. 二.解题思路 我们可以先求体积恰好为 i 时的最大重量(设为d[i]),然后取d[i]中的最大值(i ≤ C).与之前硬币问题,“面值恰好为S”就类似了.只不过加了新属性——重量,相当于把原来的无权图改成带权图,即把“+1”变成“
