Various scheduling algorithm are described in literature such as First Come First Serve (FCFS), Shortest Job First (SJF), Round Robin (RR), etc.

One criterion that must be achieved by scheduling algorithm is minimization average waiting time for a set of processes in gaining CPU allocation.

Another reason for introducing the concept is unbalanced league scheduling. There is no WAC round-robin play because the conference has 14 teams on an 18-game schedule.
