Problem 6.15

A variation of the round-robin scheduler is the regressive round-robinscheduler. This scheduler assigns each process a time quantum and apriority. The initial value of a time quantum is 50 milliseconds. However,every time a process has been allocated the CPU and uses its entire timequantum (does not block for I/O), 10 milliseconds is added to its timequantum, and its priority level is boosted. (The time quantum for aprocess can be increased to a maximum of 100 milliseconds.) When aprocess blocks before using its entire time quantum, its time quantum isreduced by 5 milliseconds, but its priority remains the same. What typeof process (CPU-bound or I/O-bound) does the regressive round-robinscheduler favor? Explain.
