                                             Treasure Exploration 复见此题,时隔久远,已忘,悲矣! 题意:用最少的机器人沿单向边走完(覆盖)全部的点.典型的最小路径覆盖,如果不懂二分图匹配可以参考:二分图大讲堂 先用floyd传递闭包,再求最大匹配,最小路径覆盖=V-最大二分匹配(最小点覆盖).为什么要用floyd传递闭包呢,每个点可以被多个机器人走过,博主就是这里没考虑到.. 我记得这个题是写过博客的....//领接矩阵匈牙利算…

题目链接: Poj 2594 Treasure Exploration 题目描述: 在外星上有n个点需要机器人去探险,有m条单向路径.问至少需要几个机器人才能遍历完所有的点,一个点可以被多个机器人经过. 解题思路: 一眼看上去是普通的最小边覆盖,但是仔细想后发现如果在原图上进行最大匹配的话,每个点只能经过一次.这样的话对于本题求出的并不是最优解,所以我们要先对原图进行传递闭包处理,然后再进行最大匹配. 这个题目点数太少H_K和匈牙利算法在空间和时间上并没有什么差,就代码复杂度而言匈牙利算法更有优…
