hdu1059 题意,现在有价值为1.2.3.4.5.6的石头若干块,块数已知,问能否将这些石头分成两堆,且两堆价值相等. 很显然,愚蠢的我一开始并想不到什么多重背包二进制优化```因为我连听都没有听过```不得不吐槽自己的知识面太窄```于是,我用了母函数写这题,母函数的做法并没有问题,但是由于这道题的数据很大,母函数轻轻松松就超时了,于是,我又很努力地在母函数循环的优化上面想出路,改改改,各种改之后依旧TLE,01背包的做法显然也是会超时的,DISCUSS里的母函数做法优化方式都是模上一个大…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=1059 题意:输入6个数,每个数ni代表价值为i的物品有ni个.求如果这些物品能均分给两个人,每个人获得的物品的总价值 相同,就输出“Can be divided.”,否则输出“Can't be divided.”:具体格式见输出格式. 思路:本来想用dfs做的,后来发现时间超限了,其实可以用多重背包来做, 每个物品的数量有限,找出是否存在几个物品的价值与物品总价值的一半相同. 参考文章:https:…
