    • An efficient cost-based scheduling method called incremental cost-based scheduling, iCBS, maps each job, based on its arrival time and SLA function, to a fixed point in the dual space of linear functions. Due to this mapping, in the dual space, the job will not change their locations over time. Instead, at the time of selecting the next job with the highest priority to execute, a line with appropriate angle in the query space is used to locate the current job with the highest CBS score in logarithmic time. Because only those points that are located on the convex hull in the dual space can be chosen, a dynamic convex hull maintaining method incrementally maintains the job with the highest CBS score over time.
    • 基于成本的有效调度方法称为增量成本调度,iCBS将每个作业的到达时间和SLA功能映射到线性函数的双重空间中的一个固定点。 由于这种映射,在双重空间中,作业将不会随着时间而改变其位置。 相反,在选择执行最高优先级的下一个作业时,在查询空间中具有适当角度的行用于以对数时间定位具有最高CBS分数的当前作业。 因为只能选择位于双重空间中的凸包上的那些点,所以动态凸包维持方法随着时间的推移逐渐维持CBS得分最高的作业。
