 题意: Alice和Bob有n个长方形,有长度和宽度,一个矩形能够覆盖还有一个矩形的条件的是,本身长度大于等于还有一个矩形,且宽度大于等于还有一个矩形.矩形不可旋转.问你Alice最多能覆盖Bob的几个矩形? 思路:贪心,先依照h将Alice和Bob的矩形排序,对于Alice的每一个矩形.假设Bob的矩形的h小于Alice的h,将Bob的w插入到集合中. 然后,在集合中找到不大于Alice矩形d的最大的Bob的d,那么这样做肯定是最优的. #include<cstdio> #includ…

题目链接:1484 - Alice and Bob's Trip 题意:BOB和ALICE这对狗男女在一颗树上走,BOB先走,BOB要尽量使得总路径权和大,ALICE要小,可是有个条件,就是路径权值总和必须在[L,R]之间,求终于这条路径的权值. 思路:树形dp,dp[u]表示在u结点的权值,往下dfs的时候顺带记录下到根节点的权值总和,然后假设dp[v] + w + sum 在[l,r]内,就是能够的,状态转移方程为 dp[u] = max{dp[v] + w }(bob) dp[u] = m…

Description Alice和Bob在玩游戏.有n个节点,m条边(0<=m<=n-1),构成若干棵有根树,每棵树的根节点是该连通块内编号最 小的点.Alice和Bob轮流操作,每回合选择一个没有被删除的节点x,将x及其所有祖先全部删除,不能操作的人输 .注:树的形态是在一开始就确定好的,删除节点不会影响剩余节点父亲和儿子的关系.比如:1-3-2 这样一条链 ,1号点是根节点,删除1号点之后,3号点还是2号点的父节点.问有没有先手必胜策略.n约为10w. 显然只要算出每颗子树的sg值就可以…

我之前做过一些博弈的题目,以为博弈都是DP,结果被坑了很多次,其实博弈有很多种,在此,把我见过的类型都搬上来. 1,HDU3951(找规律) 题意:把n枚硬币围成一个圆,让Alice和Bob两个人分别每人每次拿k(1<=k<=m)枚连续的硬币,谁能拿到最后谁赢: 思路:找规律,A拿了之后,B只要把剩下的分成偶数块,B就能赢,找到的规律就是除了m=1 && n&1是A赢,其余全是B赢,即B能够分成偶数块: #include <cstdio> #include…
题目链接 题意 : 玩台球.Alice 和 Bob,一共可以进行m次,Alice 先打.有一个白球和n个标有不同标号的球,称目标球为当前在桌子上的除了白球以外的数值最小的球,默认白球的标号为0.如果白球落入洞中,要把白球拿出来放在桌子上,如果是其他的球就不拿哪怕是犯规打进去的.每打一局(每一局代表每人打一杆)时当发生以下三种行为时算是犯规,会将相应的罚分加给对方,自己不减分. 白球没有打中任何球.将目标球的数值加到对方的分数上. 白球没有入洞且至少打中一个球,一开始没有打中目标球或者一开始同时打…
