Vertex intersection graphs of paths on a grid: characterization within block graphs
L. Alcón, F. Bonomo, M. P. Mazzoleni
We investigate graphs that can be represented as vertex intersections of horizontal and vertical paths in a grid, the so called -VPG graphs. Recognizing this class is an NP-co…

On the bend number of circular-arc graphs as edge intersection graphs of paths on a grid
L. Alcón, F. Bonomo, G. Durán +4
Golumbic, Lipshteyn and Stern \cite{Golumbic-epg} proved that every graph can be represented as the edge intersection graph of paths on a grid (EPG graph), i.e., one can associate…
