Consider a preemptive priority scheduling algorithm based on dynamically changing priorities. Larger priority numbers imply higher priority When a process is waiting for the CPU (in the ready queue, but not running), its priority changes at a rate α. When it is running, its priority changes at a rate β. All processes are given a priority of 0 when they enter the ready queue. The parameters α and β can be set to give many different scheduling algorithms. a. What is the algorithm that results from β > α > 0? b. What is the algorithm that results from α < β < 0?
