Parameterizing the quantification of CMSO: model checking on minor-closed graph classes

I Sau, G Stamoulis, DM Thilikos - arXiv preprint arXiv:2406.18465, 2024 - arxiv.org
Given a graph $ G $ and a vertex set $ X $, the annotated treewidth tw $(G, X) $ of $ X $ in $
G $ is the maximum treewidth of an $ X $-rooted minor of $ G $, ie, a minor $ H $ where the …

First-order logic with connectivity operators

N Schirrmacher, S Siebertz, A Vigny - ACM Transactions on …, 2023 - dl.acm.org
First-order logic (FO) can express many algorithmic problems on graphs, such as the
independent set and dominating set problem parameterized by solution size. However, FO …

Model-checking for first-order logic with disjoint paths predicates in proper minor-closed graph classes

PA Golovach, G Stamoulis, DM Thilikos - … of the 2023 Annual ACM-SIAM …, 2023 - SIAM
The disjoint paths logic, FOL+ DP, is an extension of First-Order Logic (FOL) with the extra
atomic predicate dp k (x 1, y 1,…, xk, yk), expressing the existence of internally vertex …

Compound logics for modification problems

FV Fomin, PA Golovach, I Sau, G Stamoulis… - ACM Transactions on …, 2023 - dl.acm.org
We introduce a novel model-theoretic framework inspired from graph modification and

Advances in Algorithmic Meta Theorems

S Siebertz, A Vigny - arXiv preprint arXiv:2411.15365, 2024 - arxiv.org
Tractability results for the model checking problem of logics yield powerful algorithmic meta
theorems of the form: Every computational problem expressible in a logic $ L $ can be …

Combing a Linkage in an Annulus

PA Golovach, G Stamoulis, DM Thilikos - SIAM Journal on Discrete …, 2023 - SIAM
A linkage in a graph of size is a subgraph of whose connected components are paths. The
pattern of a linkage of size is the set of pairs formed by the endpoints of these paths. A …
