Solving SAT via Treewidth Backdoors in Linear Time: Beyond Sparsity

Jan Dreier, Robert Ganian, Marlene Gründel +2

The Boolean Satisfiability (SAT) problem is a remarkably expressive computational problem, serving both as a cornerstone of complexity theory and as a unifying language for a wide…

Hitting Minors: Stronger Lower Bounds

Jongseo Lee, Roohani Sharma, Sebastian Wiederrecht

For a fixed finite collection of graphs , the -Minor-Free Deletion problem asks, given a graph and an integer , whether there is a set $S\subseteq…

Tractability of Hard Digraph Cut Problems on Eulerian Instances: Treewidth Reduction and Reducing CMSO to Unbreakable Eulerian Instances

Esther Galby, Roohani Sharma, Bart van der Steenhoven

Eulerian digraphs retain the directional structure of general digraphs while exhibiting a symmetry of cuts reminiscent of undirected graphs. We show that this symmetry extends beyo…

Multiway -Cut is fixed-parameter tractable

Tony Huynh, Eun Jung Kim, Sang-il Oum +2

A connectivity function on a finite set is a function that is submodular and symmetric, with . Given a connectivity function via…

Where Treewidth and Pathwidth Diverge: Towards a Uniform Kernel for Pathwidth- Deletion

Ahmed Ghazy, Jakob Greilhuber, Tim A. Hartmann +1

For a constant , Pathwidth- Deletion is the problem of deciding whether, for a given graph and integer , there is a set of size at most su…

Reducing CMSO to Unbreakable Graphs Cannot be Computable

Colin Geniet, Roohani Sharma

Lokshtanov, Ramanujan, Saurabh, and Zehavi [ICALP 2018] proved that for any CMSO formula , testing on arbitrary graphs can be reduced to testing it on -unbreakable gr…
