In the first few algorithm, the process priority number of initial set: 50-NEEDTIME Each time, priority number by 1, CPU time slice number plus 1, the process also need to reduce the number of time slice 1. In the rotation method, fixed time slice units (two time slots as a unit), the process once for each rotation, CPU time slice number plus 2, the process also need to reduce the number of time slice 2, and exit the CPU, discharged to ready queue tail, waiting for the next scheduling.
