consider following scenario, , take preemptive shortest first job executing algorithm. [1] the problem here @ timeline (3), p2 has 1 burst time available, p4 available has 2 burst time, question why p2 not continuing execution, , why p4 starting?, diagram wrong or have misunderstood in way. gantt chart has like: average waiting time should [(0+11) + 0 + 4 + 9] /4 =6.
