解决了网络流优化的快速数值逼近算法的稳定性问题,从而保证了用O(k(ε^-2+lgk)lg n)个单个流的最小成本流的计算,来定性计算最大共存流的逼近解(其中:k是共存流数,n是节点数,而ε是精度要求)是优化的.
It is shown a .solution to the stability of the fast appropriation for network flow optimization. By our method, the minimal oost flow oomputation can be ensured for O( k(ε^-2 + lg k)lg n) separate flows. Consequently, approximate solution can be obtained for the rnaximum-ooncurrent flow and it can be ensured to be optimal. In our method, the related parameters can be roughly intepreted as follows: k means the number of ooncurrent commodies, n is the number of nodes, and e is the desired precision.
