Abstract

We present the first non-trivial algorithm for the all-pairs minimum cut problem in the cut-query model. Given cut-query access to an unweighted graph G=(V,E)G=(V,E) with nn vertices, our randomized algorithm constructs a Gomory-Hu tree of GG, and thus solves the all-pairs minimum cut problem, using O~(n7/4)\tilde{O}(n^{7/4}) cut queries.
