Recognizing Visibility Graphs of Polygons with Holes and Internal-External Visibility Graphs of Polygons
Hossein Boomari, Mojtaba Ostovari, Alireza Zarei
Visibility graph of a polygon corresponds to its internal diagonals and boundary edges. For each vertex on the boundary of the polygon, we have a vertex in this graph and if two ve…
