Single-Exponential FPT Algorithms for Enumerating Secluded -Free Subgraphs and Deleting to Scattered Graph Classes

Bart M. P. Jansen, Jari J. H. de Kroon, Michał Włodarczyk

The celebrated notion of important separators bounds the number of small -separators in a graph which are 'farthest from ' in a technical sense. In this paper, we introdu…

5-Approximation for -Treewidth Essentially as Fast as -Deletion Parameterized by Solution Size

Bart M. P. Jansen, Jari J. H. de Kroon, Michal Wlodarczyk

The notion of -treewidth, where is a hereditary graph class, was recently introduced as a generalization of the treewidth of an undirected graph. Roughly…

Search-Space Reduction via Essential Vertices

Benjamin Merlin Bumpus, Bart M. P. Jansen, Jari J. H. de Kroon

We investigate preprocessing for vertex-subset problems on graphs. While the notion of kernelization, originating in parameterized complexity theory, is a formalization of provably…

Finding -Secluded Trees Faster

Huib Donkers, Bart M. P. Jansen, Jari J. H. de Kroon

We revisit the \textsc{-Secluded Tree} problem. Given a vertex-weighted undirected graph , its objective is to find a maximum-weight induced subtree whose open neighborho…

Deletion to Scattered Graph Classes I -- case of finite number of graph classes

Ashwin Jacob, Jari J. H. de Kroon, Diptapriyo Majumdar +1

Graph-modification problems, where we modify a graph by adding or deleting vertices or edges or contracting edges to obtain a graph in a {\it simpler} class, is a well-studied opti…

Vertex Deletion Parameterized by Elimination Distance and Even Less

Bart M. P. Jansen, Jari J. H. de Kroon, Michał Włodarczyk

We study the parameterized complexity of various classic vertex-deletion problems such as Odd cycle transversal, Vertex planarization, and Chordal vertex deletion under hybrid para…
