Popis: | Placing a minimum number of guards on a given watchman route in a polygonal domain is called the {\em minimum vision points problem}. We prove that finding the minimum number of vision points on a shortest watchman route in a simple polygon is APX-Hard. We then extend the proof to the class of rectilinear polygons having at most three dent orientations. Comment: 9 pages, 5 figures. A preliminary version was presented at the 38th European Workshop on Computational Geometry EuroCG 2022 |
