Maximum Cuts and Fractional Cut Covers: A Computational Study of a Randomized Semidefinite Programming Approach
Nathan Benedetto Proença, Marcel K. de Carli Silva, Cristiane M. Sato +1
We present experimental work on a primal-dual framework simultaneously approximating maximum cut and weighted fractional cut-covering instances. In this primal-dual framework, we s…

A Primal-Dual Extension of the Goemans--Williamson Algorithm for the Weighted Fractional Cut-Covering Problem
Nathan Benedetto Proença, Marcel K. de Carli Silva, Cristiane M. Sato +1
We study a weighted generalization of the fractional cut-covering problem, which we relate to the maximum cut problem via antiblocker and gauge duality. This relationship allows us…
