题意 题目链接 Sol 接下来我的实现方式和论文里不太一样 然后用bitset优化,上下走分别对应着右移/左移m位,左右走对应着右移/左移1位 我们可以直接预处理出能走的格子和不能走的格子,每次走的时候先全都走过去,再把撞到墙上的补回来即可 #include<bits/stdc++.h> #define u32 unsigned int using namespace std; const int MAXN = 1e5 + 10, SS = 150 * 150 + 150; inline in…

题目链接 (ozr attack) 考虑怎么暴力,就是先在所有非障碍格子上全放上机器人,然后枚举每一步,枚举每个机器人移动这一步,直到所有机器人都在出口位置.复杂度是\(O(nmk)\)的. 怎么优化呢,注意到每次移动都是所有机器人一起向同一个方向移动,而我们只关心每个位置上是否有机器人. 可以用bitset优化每次移动.把格子编好号后,向上移动就是整体右移\(m\)位,向左走就是整体右移一位... 还有个问题是,机器人不能往障碍上走.我们可以先把能走的机器人走过去,然后把会撞墙的机器人补回来.…

题目在这里 题意 : 问你按照图中所给的提示走,多少步能走出来??? 其实只要根据这个提示走下去就行了.模拟每一步就OK,因为下一步的操作和上一步一样,所以简单dfs.如果出现loop状态,只要记忆每个所到的点的第一次的步数,最后总步数减掉它即可 /************************************************************************* > File Name: poj1573.cpp > Author: YeGuoSheng >…
