β¦ Synopsis
We give a simple algorithm for ΓΏnding a minimum T -cut. At present, all known e cient algorithms for this problem go through the computation of a Gomory-Hu tree. While our algorithm bases on the same fundamental properties of uncrossing as the previous methods, still it provides an ad hoc solution. This solution is easier to implement and faster to run. Our results extend to the whole of symmetric submodular functions.

The traditional min-cut problem involves finding a cut with minimum weight between two specified vertices. The planar multiway cut problem is a NP-hard generalization of the min-cut problem. It involves separating a weighted planar graph with k specified vertices into k components such that the tota
