WebJan 1, 2005 · We prove that finding the minimum number of vision points (i.e., static guards) along a shortest watchman route is NP-hard. We provide a linear time algorithm to compute the best set of static guards in a histogram (Manhattan skyline) polygon. The m -watchmen problem (minimize total length of routes for m watchmen) is NP-hard for simple polygons. WebA watchman, in the terminology of art galleries, is a mobile guard. We consider two watchman problems for spiral polygons, a subclass of simple polygons. The first is to find …
