我们给出了一个算法,以最小化总完成时间在线单机上,使用重新启动,与3/2的竞争比。在不使用重启的情况下,确定性算法的最优竞争比为2,随机算法的最优竞争比为de/(e-1)= 1.582。这是第一个重新启动算法,以最大限度地减少总完成时间,被证明是优于一个算法,不重新启动。
We give an algorithm to minimize the total completion time on-line on a single machine, using restarts, with a competitive ratio of 3/2. The optimal competitive ratio without using restarts is 2 for deterministic algorithms ande/(e—1)≈ 1.582 for randomized algorithms. This is the first restarting algorithm to minimize the total completion time that is proved to be better than an algorithm that does not restart.
