2.In this paper, it is proved that when the condition is not satisfied, the gap between the sub-optima solution and the global optima (expressed by a percentage of the global optima) is no more than the ratio between the left resources of the sub-optimal solution and the total resources, and is no more than the ratio between the cutoff resources obtained by one application and the total resources.
论文证明了：当该条件不满足时，次优解与全局最优解的距离（用百分比表示）不大于次优解中未分配的带宽占总数的百分比，不大于单个应用在临界状态时获得的无线资源占系统总量的百分比。收藏指正
