PACE Solver Description
DOI: 10.4230/LIPIcs.IPEC.2024.35
PACE Solver Description: OCMu64, a Solver for One-Sided Crossing Minimization

Authors: Ragnar Groot Koerkamp and Mees de Vries

Published in: LIPIcs, Volume 321, 19th International Symposium on Parameterized and Exact Computation (IPEC 2024)

Abstract
Given a bipartite graph (A,B), the one-sided crossing minimization (OCM) problem is to find an ordering of the vertices of B that minimizes the number of edge crossings when drawn in the plane. We introduce the novel strongly fixed, practically fixed, and practically glued reductions that maximally generalize some existing reductions. We apply these in our exact solver OCMu64, that directly uses branch-and-bound on the ordering of the vertices of B and does not depend on ILP or SAT solvers.

PACE Solver Description
DOI: 10.4230/LIPIcs.IPEC.2020.29
PACE Solver Description: tdULL

Authors: Ruben Brokkelkamp, Raymond van Venetië, Mees de Vries, and Jan Westerdiep

Published in: LIPIcs, Volume 180, 15th International Symposium on Parameterized and Exact Computation (IPEC 2020)

Abstract
We describe tdULL, an algorithm for computing treedepth decompositions of minimal depth. An implementation was submitted to the exact track of PACE 2020. tdULL is a branch and bound algorithm branching on inclusion-minimal separators.
