For example, I have an 8-node digraph with capacities on each arc and want to find the overall min-cut separating some node pairs such as 8 and 1, 6 and 3, 7 and 1. The algorithm of Hao and Orlin (1994) cannot solve my problem. - { E" }' f% M" r # }, C A! C5 a% p4 ^: k3 f0 y! f2 h
不好意思,我用英文至少为了把问题说的更清楚一点
