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…
Dominated balanced separators in wheel-induced-minor-free graphs
Maria Chudnovsky, J. Pascal Gollin, Matjaž Krnc +1
Gartland and Lokshtanov conjectured that every graph that excludes some planar graph as an induced minor has a balanced separator, that is, a separator whose deletion leaves every…
Induced matching treewidth and tree-independence number, revisited
Noga Alon, Martin Milanič, Paweł Rzążewski
We study two graph parameters defined via tree decompositions: tree-independence number and induced matching treewidth. Both parameters are defined similarly as treewidth, but with…
Perfect phylogenies via the Minimum Uncovering Branching problem: efficiently solvable cases
Narmina Baghirova, Esther Galby, Martin Milanič
In this paper, we present new efficiently solvable cases of the Minimum Uncovering Branching problem, an optimization problem with applications in cancer genomics introduced by Huj…
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…
Excluding an induced wheel minor in graphs without large induced stars
Mujin Choi, Claire Hilaire, Martin Milanič +1
We study a conjecture due to Dallard, Krnc, Kwon, Milanič, Munaro, Štorgel, and Wiederrecht stating that for any positive integer and any planar graph , the class of all $K_…
