Better Bounds for Online Scheduling

  title={Better Bounds for Online Scheduling},
  author={Susanne Albers},
We study a classical problem in online scheduling. A sequence of jobs must be scheduled on m identical parallel machines. As each job arrives, its processing time is known. The goal is to minimize the makespan. Bartal, Fiat, Karlo and Vohra [3] gave a deterministic online algorithm that is 1.986-competitive. Karger, Phillips and Torng [11] generalized the algorithm and proved an upper bound of 1.945. The best lower bound currently known on the competitive ratio that can be achieved by… CONTINUE READING
