意甲冠军:N个人M通过主打歌有自己的期望,每个问题发送人玩.它不能超过随机播放的次数1,追求最大业绩预期 (1 ≤ N ≤ 10,1 ≤ M ≤ 1000). 主题链接:pid=5045" target="_blank">http://acm.hdu.edu.cn/showproblem.php?pid=5045 -->>设dp[i][j]表示已出战了前i - 1道题目,已出战的人的状态序列为j,如今要做第i道题目的最大期望.则最后要求的结果为max{dp[…

pid=5045">主题链接~~> 做题感悟:比赛时这题后来才写的,有点小尴尬.两个人商议着写写了非常久才写出来,I want to Powerful ,I believe me . 解题思路: 遗憾 ! 感觉领悟能力太低 .由于随意时刻随意两个人做的题不超过 1 题 ,so~>  必须是一轮一轮的来(n 道题一轮),每一个人在一轮中仅仅能做一题.假设多做一题就,有可能某个人没选,某个人选择了两道,这样就不符合规定了 . 用 1  代表选择.0  代表没选择.进行某一行的时候就…

题解:我们使用一个二位数组dp[i][j]记录进行到第i个任务时,人组合为j时的最大和(这里的j我们用二进制的每位相应一个人). 详细见代码: #include <iostream> #include <cstdio> #include <cstring> #include <cmath> using namespace std; typedef long long ll; double s[11][1010]; double dp[1010][1050];…

HDU 5045 5047 5050 5053 太菜了,名额差点没保住.吓尿..赶紧开刷树链抛分 5045:状压DP.压缩10个人.因为两个人不能差2以上,所以能够用01表示 5047:推推公式就可以,每次交线多4条 5050:求GCD.用java大叔就可以 5053:签到题 代码: 5045: #include <cstdio> #include <cstring> #include <algorithm> using namespace std; const int…

http://acm.hdu.edu.cn/showproblem.php?pid=5045 题意:n个学生m道题,一个n*m的矩阵代表第n个学生解第m题AC的概率,任意两学生做题数差距不能大于1,问AC所有题目概率的最大值 由于限制条件,所以一定是以n个学生为单位,一轮一轮的做题,直到做m题为止,这样题目就转化为了一个状态压缩dp,当状态为(1<<n)-1的时候清空状态 dp[i][j]表示AC 前i道题目状态为j的最大值 #include <iostream> #include…
