题意:有K台挤奶机,C头奶牛,每个挤奶机每天只能为M头奶牛服务,下面给的K+C的矩阵,是形容相互之间的距离,求出来走最远的那头奶牛要走多远   输入数据: 第一行三个数 K, C, M  接下来是  (K+C)*(K+C)的矩阵 表示每个物体之间的距离, 0 表示两者之间是不通的. 挤奶机 1, 挤奶机2 .... 挤奶机 K, 奶牛1,奶牛2...奶牛M 题目思路: 对输入进来的数据先进行闭包传递,然后再对奶牛到挤奶机的距离进行二分枚举,枚举出来的值进行多重匹配 #include<stdio.…

题目链接: Poj 2289 Jamie's Contact Groups 题目描述: 给出n个人的名单和每个人可以被分到的组,问将n个人分到m个组内,并且人数最多的组人数要尽量少,问人数最多的组有多少人? 解题思路: 二分图多重匹配相对于二分匹配来说不再是节点间的一一对应,而是Xi可以对应多个Yi.所以我们就需要一个限制(Xi最多匹配几个Yi).当Yi需要匹配Xi的时候,Xi的匹配未到上限,直接匹配,否则进行增广路.其实是二分图多重匹配的模板题,再套一个二分枚举最多组的人数就OK咯.下面就上板…
