Train Marshalling Is Fixed Parameter Tractable [PDF]
The train marshalling problem is about reordering the cars of a train using as few auxiliary rails as possible. The problem is known to be NP-complete. We show that it is fixed parameter tractable (FPT) with the number of auxiliary rails as parameter.

The “Art of Trellis Decoding” Is Fixed-Parameter Tractable [PDF]
50 pages. Accepted to SODA 2016 under the title "constructive algorithms for path-width of matroids". We added several figures to improve its presentation. We found a mistake in the proof of Lemma 3.24 of the previous version.

Parameterized Algorithms for (r,l)-Partization
We consider the (r,l)-Partization problem of finding a set of at most k vertices whose deletion results in a graph that can be partitioned into r independent sets and l cliques.

Parameterized Complexity of 1-Planarity
We consider the problem of drawing graphs with at most one crossing per edge. These drawings, and the graphs that can be drawn in this way, are called $1$-planar.

Scheduling Meets Fixed-Parameter Tractability
Fixed-parameter tractability analysis and scheduling are two core domains of combinatorial optimization which led to deep understanding of many important algorithmic questions. However, even though fixed-parameter algorithms are appealing for many reasons, no such algorithms are known for many fundamental scheduling problems.

Treewidth of display graphs: bounds, brambles and applications
Phylogenetic trees and networks are leaf-labelled graphs used to model evolution. Display graphs are created by identifying common leaf labels in two or more phylogenetic trees or networks.

The maximum 2-edge-colorable subgraph problem and its fixed-parameter tractability
A $k$-edge-coloring of a graph is an assignment of colors $\{1,...,k\}$ to edges of the graph such that adjacent edges receive different colors. In the maximum $k$-edge-colorable subgraph problem we are given a graph and an integer $k$, the goal is to ...

Reconstructing Generalized Staircase Polygons with Uniform Step Length
Visibility graph reconstruction, which asks us to construct a polygon that has a given visibility graph, is a fundamental problem with unknown complexity (although visibility graph recognition is known to be in PSPACE).

Deciding the Feasibility and Minimizing the Height of Tangles
We study the following combinatorial problem. Given a set of $n$ y-monotone Jordan curves, called wires, a tangle determines the order of the wires on a number of horizontal layers such that the orders of the wires on any two consecutive layers differ ...
