Round-robin schedulers normally maintain a list of all runnable processes, with each process occurring exactly once in the list. What would happen if a process occurred twice in the list? Can you think of any reason for allowing this?

If a process occurs twice in that list then it would be executed twice by the processor.
The reason for allowing this may be to increase priority of a process as it will be executed as many number of times as it is in the list.

Another reason might be the that other process execution time finished as the process listed twice in the list is the only process that required execution.

A process will gets more quanta per scheduling cycles and also it is used to give important process a larger share of CPU

Andrew S. Tanenbaum (OS) Edition 4 Exercise 2 Question 45 (Page No. 177 - 178)
Five batch jobs. $A$ through $E$, arrive at a computer center at almost the same time. They have estimated running times of $10, 6, 2, 4,$ and $8$ ... through $(d),$ assume that only one job at a time runs, until it finishes. All jobs are completely CPU bound.

Andrew S. Tanenbaum (OS) Edition 4 Exercise 2 Question 44 (Page No. 177)
Five jobs are waiting to be run. Their expected run times are $9, 6, 3, 5,$ and $X$. In what order should they be run to minimize average response time? $($Your answer will depend on $X.)$

Andrew S. Tanenbaum (OS) Edition 4 Exercise 2 Question 43 (Page No. 177)
Measurements of a certain system have shown that the average process runs for a time $T$ before blocking on $I/O$. A process switch requires a time $S$, which is effectively wasted (overhead). For round-robin scheduling with quantum $Q$, give a formula ... $Q > T$ $S < Q < T $ $Q = S$ $Q\: \text{nearly}\: 0$
