组合游戏 Nim游戏的一个变形 题解请看金海峰的博客 以下为引用: 分析:我们把棋子按位置升序排列后,从后往前把他们两两绑定成一对.如果总个数是奇数,就把最前面一个和边界(位置为0)绑定. 在同一对棋子中,如果对手移动前一个,你总能对后一个移动相同的步数,所以一对棋子的前一个和前一对棋子的后一个之间有多少个空位置对最终的结果是没有影 响的.于是我们只需要考虑同一对的两个棋子之间有多少空位.我们把每一对两颗棋子的距离(空位数)视作一堆石子,在对手移动每对两颗棋子中靠右的那一颗 时,移动几位就相当于…

POJ 1704 题目链接 关于阶梯博弈有如下定理: 将所有奇数阶梯看作n堆石头,做Nim,将石头从奇数堆移动到偶数堆看作取走石头,同样地,异或值不为0(利己态)时,先手必胜. 定理证明看此博:http://blog.csdn.net/kk303/article/details/6692506 以下是POJ 1704的AC代码: //棋子只能往左走(最左有界线),可以走任意多格(>=1) //而且棋子不能越过在它前面的棋子(它左边的棋子) //每个格最多放一个棋子,说明棋子也不能走到另一个棋子所…

题目链接题意:如图,Georgia和Bob在玩游戏.一个无限长的棋盘上有N个旗子,第i个棋子的位置可以用Pi表示.现在Georgia先走.每个人每一次可以把一枚棋子向左移动任意个格子,但是不能超越其他棋子,也不能和其他棋子处在同一个格子里.如果轮到某一个人的时候Ta再也不能移动棋子了,就判负.现在每个测试数据给定一种情况,如果Georgia会赢,输出“Georgia will win”,如果Bob会赢,输出“Bob will win”,如果不确定,输出“Not sure”.两个人都知道获胜策略是…
