Predicting CPU Burst Times

Equation: $ \tau_{n+1} = \alpha t_n + (1-\alpha) \tau_n$

$ t_n : $ length of the current burst

$ \tau_n : $ predicted length for current burst

$ \tau_{n+1} : $ prediction for the next burst

$ \alpha : $ the weight. If $ \alpha $ is higher, the most recent burst affects the next prediction more.

Type values into the "Actual Burst" row. It will then calculate the predicted bursts.

Burst Number ( $n$ ): 1 2 3 4 5 6
Predicted Burst ( $\tau$ ):
Actual Burst ( $t$ ):
