求non-preemptive Shortest Job First与Round Robin的平均等待时间。 输入为两个array,一个为到达时间,一个为执行时间。对于Round Robin还另外有time slice. 直接看代码吧。思路挺直接的,就想象自己就是处理器,有一个CPU时间一直在走,到点该做什么做什么。不过得注意细节。 还有想清楚waiting time是怎么得到的,比...
Minimizing waiting time for tasks waiting in the queue for execution is one of the important scheduling cri-teria which took a wide area in scheduling preemptive tasks. In this paper we present Changeable Time Quan-tum (CTQ) approach combined with the round-robin algorithm, we try to adjust ...

The end of the round-robin stages at the 2023 ATP finals is nearing, and there are numerous permutations regarding which players can progress into the weekend’s knockout stages. Djokovic, Sinner and Rune are the three live players in the green group, while Alcaraz and Zverev both have chanc...
Round Robin (RR) Scheduling is the basis of time sharing environment. It is the combination of First Come First Served (FCFS) scheduling algorithm and preemption among processes. It is basically used in a time sharing operating system. It switches from one process to another process in a time...
