Q. A Process has the following information while scheduling by Shortest Process Next/Shortest Job First. Last three runs of a process are 5, 6, 5 and last predicted burst time of a process is 7. Here α = 0.8. Now predict the next CPU burst time using exponential averaging.
Answer:
Given
Actual Burst Time () = (5, 6, 5)
Then we calculate (Predict) here = ?
As per the formula of exponential averaging:
So, the next CPU burst time is predicted 5.296 using exponential averaging.
