APX-Hardness of the Minimum Vision Points Problem

Mayank Chaturvedi, Bengt J. Nilsson

英文摘要:

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.
