摘要
We investigate graphs that can be represented as vertex intersections of horizontal and vertical paths in a grid, known as B-0-VPG graphs. Recognizing these graphs is an NP-hard problem. In light of this, we focus on their subclasses. In the paper, we describe polynomial time algorithms for recognizing chordal B-0-VPG graphs, and for recognizing B-0-VPG graphs that have a representation on a grid with 2 rows.
