PACE Solver Description: Sallow: A Heuristic Algorithm for Treedepth Decompositions

pdf-format:
LIPIcs-IPEC-2020-36.pdf (0.4 MB)

Abstract

We describe a heuristic algorithm for computing treedepth decompositions, submitted for the https://pacechallenge.org/2020 challenge. It relies on a variety of greedy algorithms computing elimination orderings, as well as a Divide & Conquer approach on balanced cuts obtained using a from-scratch reimplementation of the 2016 FlowCutter algorithm by Hamann & Strasser [Michael Hamann and Ben Strasser, 2018].
