Intersection Dimension and Graph Invariants

open access: yesDiscussiones Mathematicae Graph Theory, 2021
We show that the intersection dimension of graphs with respect to several hereditary properties can be bounded as a function of the maximum degree. As an interesting special case, we show that the circular dimension of a graph with maximum degree Δ is at

Tractable Inference for Hybrid Bayesian Networks with NAT-Modeled Dynamic Discretization

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference, 2022
Hybrid BNs (HBNs) extend Bayesian networks (BNs) to both discrete and continuous variables. Among inference methods for HBNs, we focus on dynamic discretization (DD) that converts HBN to discrete BN for inference.

Tight Bounds for Hypercube Minor‐Universality

open access: yesJournal of Graph Theory, Volume 112, Issue 4, Page 433-437, August 2026.
ABSTRACT A graph G is m‐minor‐universal if every graph H with at most m edges and no isolated vertices is contained as a minor in G. Recently, Benjamini, Kalifa and Tzalik proved that there is an absolute constant c > 0 such that the d‐dimensional hypercube Q d is ( c ⋅ 2 d / d)‐minor‐universal, while there is an absolute constant K > 0 such that Q d ...

On the k-rainbow domination in graphs with bounded tree-width

open access: yesElectronic Journal of Graph Theory and Applications, 2021
Given a positive integer k and a graph G = (V, E), a function f from V to the power set of Ik is called a k-rainbow function if for each vertex v ∈ V, f(v)=∅ implies ∪u ∈ N(v)f(u)=Ik where N(v) is the set of all neighbors of vertex v and Ik = {1, …, k ...

An Improved Quasi‐Isometry Between Graphs of Bounded Cliquewidth and Graphs of Bounded Treewidth

open access: yesJournal of Graph Theory, Volume 112, Issue 4, Page 409-420, August 2026.
ABSTRACT Cliquewidth is a dense analogue of treewidth. It can be deduced from recent results by Hickingbotham [arXiv:2501.10840] and Nguyen, Scott, and Seymour [arXiv:2501.09839] that graphs of bounded cliquewidth are quasi‐isometric to graphs of bounded treewidth. We improve on this by showing that graphs of cliquewidth k admit a partition with ‘local,

Treewidth Versus Clique Number. V. Further Connections With Tree‐Independence Number

open access: yesJournal of Graph Theory, Volume 112, Issue 3, Page 337-351, July 2026.
ABSTRACT We continue the study of ( tw , ω )‐bounded graph classes, that is, hereditary graph classes in which large treewidth is witnessed by the presence of a large clique, and the relation of this property to boundedness of the tree‐independence number, a graph parameter introduced independently by Yolov in 2018 and by Dallard, Milanič, and Štorgel ...

Discovering Treewidth

open access: yes, 2005
Treewidth is a graph parameter with several interesting theoretical and practical applications. This survey reviews algorithmic results on determining the treewidth of a given graph, and finding a tree decomposition of small width. Both theoretical results, establishing the asymptotic computational complexity of the problem, as experimental work on ...
