A Faster Algorithm for Independent Cut

Vsevolod Chernyshev, Johannes Rauch, Dieter Rautenbach +1

The previously fastest algorithm for deciding the existence of an independent cut had a runtime of , where is the order of the input graph. We improve…

GridOT -- a discrete optimal transport solver on grids

Johannes Rauch, Leo Zanotti

We provide an improved implementation of Schmitzer's sparse multi-scale algorithm for discrete optimal transport on grids. We report roughly 2-4 times faster runtimes on the DOTmar…

Cutwidth and Crossings

Johannes Rauch, Dieter Rautenbach

We provide theoretical insights around the cutwidth of a graph and the One-Sided Crossing Minimization (OSCM) problem. OSCM was posed in the Parameterized Algorithms and Computatio…

weberknecht -- a One-Sided Crossing Minimization solver

Johannes Rauch

We describe the implementation of the exact solver weberknecht and the heuristic solver weberknecht_h for the One-Sided Crossing Minimization problem.

On Conflict-Free Cuts: Algorithms and Complexity

Johannes Rauch, Dieter Rautenbach, Uéverton S. Souza

One way to define the Matching Cut problem is: Given a graph , is there an edge-cut of such that is an independent set in the line graph of ? We propose the more…

Exact and Parameterized Algorithms for the Independent Cutset Problem

Johannes Rauch, Dieter Rautenbach, Uéverton S. Souza

The Independent Cutset problem asks whether there is a set of vertices in a given graph that is both independent and a cutset. Such a problem is -complete even when th…
