On the parameterized complexity of computing good edge-labelings
Davi de Andrade, Júlio Araújo, Laure Morelle +2
A good edge-labeling (gel for short) of a graph is a function such that, for any ordered pair of vertices of , there do not exist two dist…
Dynamic programming on bipartite tree decompositions
Lars Jaffke, Laure Morelle, Ignasi Sau +1
We revisit a graph width parameter that we dub bipartite treewidth (btw). Bipartite treewidth can be seen as a common generalization of treewidth and the odd cycle transversal numb…
Graph modification of bounded size to minor-closed classes as fast as vertex deletion
Laure Morelle, Ignasi Sau, Dimitrios M. Thilikos
A replacement action is a function that maps each graph to a collection of graphs of size at most . Given a graph class , we consider a gener…
Excluding Pinched Spheres
Laure Morelle, Evangelos Protopapas, Dimitrios M. Thilikos +1
The pinched sphere is the pseudo-surface obtained by identifying two distinct points of the sphere. We provide a structural characterization of graphs exclud…
A note on locating-dominating sets in twin-free graphs
Nicolas Bousquet, Quentin Chuet, Victor Falgas-Ravry +2
In this short note, we prove that every twin-free graph on vertices contains a locating-dominating set of size at most . This improves the earlier bou…
