A Fast Algorithm for Multi-Machine Scheduling Problems with Jobs of Equal Processing Times

Alejandro Lopez-Ortiz & Claude-Guy Quimper
Consider the problem of scheduling a set of tasks of length p without preemption on $m$ identical machines with given release and deadline times. We present a new algorithm for computing the schedule with minimal completion times and makespan. The algorithm has time complexity O(min(1,p/m)n^2) which improves substantially over the best known algorithm with complexity O(mn^2).
