Starvation is possible. • Multilevel Queuing: An implementation (approximation) of SJF. • Lottery Scheduling: Fairer with a low average waiting time
Users with root privileges can easily implement and add new scheduling classes by adhering to a predefined interface. Each scheduling class gives each of its

algorithms behind a multi-level feedback queue; although the specifics of many implemented MLFQs differ [E95] most approaches are similar.
In this paper we have implemented MLFQ technique using small burst time for the first queue thus making it analogous to RR scheduling and using SJF prior to RR
Multilevel feedback queues use past behavior to predict the future and assign job priorities => overcome the prediction problem in SJF
We have described a scheduling approach known as the Multi-Level Feedback Queue (MLFQ) Hopefully you can now see why it is called that: it has multiple levels
