摘要 本文研究平等机上的在线排序问题,优化目标是使总完工时间最小,算法SSPT是此问题的一类在线算法,论文引入一个拟时间表,此时间表具有SRPT时间表的部分性质,论文通过此辅助时间表证明了SSPT算法是(3-1/m)-competitive的。 In this paper,we consider the problem of non-preemptive scheduling jobs on-line on identical parallel machines with the objective to minimize total completion time.We give a general algorithm for the m-machine problem.We construct a new schedule which has some character of SRPT schedule.Through this assistant schedule,we show that the algorithm SSPT for the problem is(3-1/m)-ccompetitive.
