Leader Election And Local Identifiers For 3D Programmable Matter

Nicolas Gastineau, Wahabou Abdou, Nader Mbarek +1

In this paper, we present two deterministic leader election algorithms for programmable matter on the face-centered cubic grid. The face-centered cubic grid is a 3-dimensional 12-r…

Coloring of the dth power of the face-centered cubic grid

Nicolas Gastineau, Olivier Togni

The face-centered cubic grid is a three dimensional 12-regular infinite grid. This graph represents an optimal way to pack spheres in the three-dimensional space. In this grid, the…

On packing chromatic number of subcubic outerplanar graphs

Nicolas Gastineau, P{ř}emysl Holub, Olivier Togni

Although it has recently been proved that the packing chromatic number is unbounded on the class of subcubic graphs, there exists subclasses in which the packing chromatic number i…
