It would be V[i, j] - vi. So, select P3 and execute 6 ms (since B.T(P3)=6 which is higher than B.T(P2) = 4), As P3 is executing thus, Process P4 will wait in the waiting queue. 'algorithm' is not correct at all and will fail at runtime. For example, since the number of workers per work shift needs to be an integer and needs to be greater than 0 we write: Linear programming aims to either minimize or maximize some numerical values such as costs, profit, etc. Christian Science Monitor: a socially acceptable source among conservative Christians? However, with the use of set data structure (find and union), the algorithm runs nearly in O(N) time. Profit earned only if the job is completed on or before its deadline. From a managers point of view, an optimal solution is to minimize the number of workers per shift to save money while still assigning enough workers for each time window. - User App Web Version Furthermore, the pandas dataframe must be selected from todays datetime and 4 hours back.

Since, completion time (C.T) can be directly determined by Gantt chart, and, Turn Around Time (TAT)= (Completion Time) (Arrival Time), Also, Waiting Time (WT)= (Turn Around Time) (Burst Time), Total Turn Around Time = 40 msSo, Average Turn Around Time = 40/4 = 10.00 ms, And, Total Waiting Time = 20 msSo, Average Waiting Time = 20/4 = 5.00 ms. Example-2: Consider the following table of arrival time and burst time for four processes P1, P2, P3, P4 and P5.
