PACE Solver Description: DreyFVS Bathie, Gabriel Berthe, Gaétan Coudert-Osmont, Yoann Desobry, David Reinald, Amadeus Rocton, Mathis Directed Feedback Vertex Set Heuristic Sinkhorn algorithm Local search We describe DreyFVS, a heuristic for Directed Feedback Vertex Set submitted to the 2022 edition of Parameterized Algorithms and Computational Experiments Challenge. The Directed Feedback Vertex Set problem asks to remove a minimal number of vertices from a digraph such that the resulting digraph is acyclic. Our algorithm first performs a guess on a reduced instance by leveraging the Sinkhorn-Knopp algorithm, to then improve this solution by pipelining two local search methods.
