A Note on the Complexity of One-Sided Crossing Minimization of Trees

Computational Complexity 2023-06-28 v1

Abstract

In 2011, Harrigan and Healy published a polynomial-time algorithm for one-sided crossing minimization for trees. We point out a counterexample to that algorithm, and show that one-sided crossing minimization is NP-hard for trees.
