As we all know, machine scheduling is a very classical problem in computer science and has been studied for a very long history. Scheduling problems differ widely in the nature of the constraints that must be satisfied and the type of schedule desire…

题目大意:机器调度问题,同一个任务可以在A,B两台不同的机器上以不同的模式完成.机器的初始模式是mode_0,但从任何模式改变成另一个模式需要重启机器.求完成所有工作所需最少重启次数. =================================================== 对于任务(i,x,y),我们在A机mode_x与B机mode_y之间连一条边.这样,题目就变成了一个二分图,我们的目的是完成所有任务,即覆盖所有线段,题目要求选择最少的点,使得每个线段至少有一个端点被选中(这个…
