Rank-width and vertex-minors

S Oum - Journal of Combinatorial Theory, Series B, 2005 - Elsevier
The rank-width is a graph parameter related in terms of fixed functions to clique-width but
more tractable. Clique-width has nice algorithmic properties, but no good “minor” relation is …

Vertex-minors, monadic second-order logic, and a conjecture by Seese

B Courcelle, S Oum - Journal of Combinatorial Theory, Series B, 2007 - Elsevier
We prove that one can express the vertex-minor relation on finite undirected graphs by
formulas of monadic second-order logic (with no edge set quantification) extended with a …

Deleting, Eliminating and Decomposing to Hereditary Classes Are All FPT-Equivalent∗

A Agrawal, L Kanesh, D Lokshtanov, F Panolan… - Proceedings of the 2022 …, 2022 - SIAM
Vertex-deletion problems have been at the heart of parameterized complexity throughout its
history. Here, the aim is to determine the minimum size (denoted by mod ℋ) of a modulator …

Vertex deletion problems have been at the heart of numerous major advances in Algorithms
and Combinatorial Optimization, and especially so in the area of Parameterized Complexity …

The rank-width of edge-coloured graphs

MM Kanté, M Rao - Theory of Computing Systems, 2013 - Springer
AC-coloured graph is a graph, that is possibly directed, where the edges are coloured with
colours from the set C. Clique-width is a complexity measure for C-coloured graphs, for finite …

[BOOK][B] Graphs of bounded rank-width

SI Oum - 2005 - search.proquest.com
We define rank-width of graphs to investigate clique-width. Rank-width is a complexity
measure of decomposing a graph in a kind of tree-structure, called a rank-decomposition …

Decomposing a signed graph into rooted circuits

R McCarty - arxiv preprint arxiv:2308.01456, 2023 - arxiv.org
We prove a precise min-max theorem for the following problem. Let $ G $ be an Eulerian
graph with a specified set of edges $ S\subseteq E (G) $, and let $ b $ be a vertex of $ G …

[HTML][HTML] Linear rank-width and linear clique-width of trees

I Adler, MM Kanté - Theoretical Computer Science, 2015 - Elsevier
We show that for every forest T the linear rank-width of T is equal to the path-width of T, and
the linear clique-width of T equals the path-width of T plus two, provided that T contains a …
