hdu - 1150 Machine Schedule (二分图匹配最小点覆盖)

http://acm.hdu.edu.cn/showproblem.php?pid=1150 有两种机器,A机器有n种模式,B机器有m种模式,现在有k个任务需要执行,没切换一个任务机器就需要重启一次, 如果任务i在机器A上执行,A机器需要一个对应的模式A,如果在机器B上执行,机器A需要一个模式B. 一直就是机器A在切换模式,现在让你安排一种合理的任务执行顺序,让机器重启次数最少. 每个任务之间连一条边.二分图的最小顶点覆盖就是求最少的点可以连接所有的边,然后转化成最大匹配即可. 这题就是初始状态

题目大意:有两台机器A和B,A机器有n种工作方式,B机器有m种工作方式.共有k个任务.每个任务恰好在一条机器上运行. 如果任务在A机器上运行,就需要转换为模式Xi,如果在B机器上运行,就需要转换为模式Yi. 每台机器上的任务可以按照任意顺序执行,但是每台机器每转换一次模式需要重启一次. 请合理为每个任务安排一台机器并合理安排顺序,使得机器重启次数尽量少. 邻接矩阵 #include <iostream> #include <cstdio> #include <cstring&
