Approximate minimum cuts and their enumeration

Data Structures and Algorithms 2022-12-01 v1

Abstract

We show that every α\alpha-approximate minimum cut in a connected graph is the unique minimum (S,T)(S,T)-terminal cut for some subsets SS and TT of vertices each of size at most 2α+1\lfloor2\alpha\rfloor+1. This leads to an alternative proof that the number of α\alpha-approximate minimum cuts in a nn-vertex connected graph is nO(α)n^{O(\alpha)} and they can all be enumerated in deterministic polynomial time for constant α\alpha.
