Determining the Complexity of Chromatic Sum in Classes Defined by a Set of Forbidden Graphs

Clément Dallard, Daniël Paulusma, Erik Jan van Leeuwen

The Chromatic Sum problem asks, given a graph and an integer , whether admits a colouring with sum . We study the complexity of Chromatic S…

Awesome graph parameters

Kenny Bešter Štorgel, Clément Dallard, Vadim Lozin +2

For a graph , we denote by the size of a maximum independent set and by the size of a maximum clique in . Our paper lies on the edge of two lines of research, r…

Layered tree-independence number and clique-based separators

Clément Dallard, Martin Milanič, Andrea Munaro +1

Motivated by a question of Galby, Munaro, and Yang (SoCG 2023) asking whether every graph class of bounded layered tree-independence number admits clique-based separators of sublin…

Treewidth versus clique number. IV. Tree-independence number of graphs excluding an induced star

Clément Dallard, Matjaž Krnc, O-joung Kwon +4

Many recent works address the question of characterizing induced obstructions to bounded treewidth. In 2022, Lozin and Razgon completely answered this question for graph classes de…

Induced Minor Models. I. Structural Properties and Algorithmic Consequences

Nicolas Bousquet, Clément Dallard, Maël Dumas +4

A graph is said to be an induced minor of a graph if can be obtained from by a sequence of vertex deletions and edge contractions. Equivalently, is an induced m…

Functionality of box intersection graphs

Clément Dallard, Vadim Lozin, Martin Milanič +2

Functionality is a graph complexity measure that extends a variety of parameters, such as vertex degree, degeneracy, clique-width, or twin-width. In the present paper, we show that…
