比较形象的是地图每个点都拆成三个点,这三个点限制流量为0或1,于是再一分为二,这样每个点都被拆成6个点... 其实拆两个点,连容量为柱子高的边,这样就行了.. 这题我掉坑了,“1 lizard was left behind.”..虽然样例都把一切都说了..要注意细节.. #include<cstdio> #include<cstring> #include<queue> #include<algorithm> using namespace std; #d…

题目链接 题意 给定一张网格,格子中有些地方有柱子,有些柱子上面有蜥蜴. 每个柱子只能承受有限只蜥蜴从上面经过.每只蜥蜴每次能走到相距曼哈顿距离\(\leq k\)的格子中去. 问有多少只蜥蜴能走出网格. 分析 参考博文 拆点 因为这道题中的容量不是限制在边上,而是限制在点上的,所以可以考虑将一个点拆成两个点,中间再加一条边,边的容量即为原先点上的值. 想法很重要. 建图 对于起始有蜥蜴的点,从源点\(s\)连一条容量为\(1\)的边到它: 对于中间点,拆成两点:点\(1\)到点\(2\)的容量…

题目 题意: t组输入,然后地图有n行m列,且n,m<=20.有一个最大跳跃距离d.后面输入一个n行的地图,每一个位置有一个值,代表这个位置的柱子可以经过多少个猴子.之后再输入一个地图'L'代表这个位置刚开始有一个猴子.'.'代表这个位置刚开始没有猴子 题解: 1 //其实这道题就是建图比较麻烦,其他还是可以的.但是最大的坑点就是 2 //1.输出的时候的单复数,没有逃出来的猴子数为0.1的时候,要输出lizard和was,否则要输出lizards和were.我也是醉了 3 //2.他那个条约最…

Leapin' Lizards 题目大意: 在一个网格地图中有一些高度不同的石柱,一些石柱上站着一些蜥蜴,你的任务是让尽量多的蜥蜴逃到边界外. 每行每列中相邻石柱的距离为1,蜥蜴的跳跃距离是d,即蜥蜴可以跳到平面距离不超过d的任何一个石柱上.石柱都不稳定,每次当蜥蜴跳跃时,所离开的石柱高 度减1(如果仍然落在地图内部,则到达的石柱高度不变),如果该石柱原来高度为1,则蜥蜴离开后消失.以后其他蜥蜴不能落脚.任何时刻不能有两只蜥蜴在同 一个石柱上. 这个应该还算是比较难的网络流的题目了吧, 至少对我…
