A Triangulation and Guard Sufficiency Set of the Hierarchy of Simple Polygons  

Yang, Tae-Cheon (경성대학교 컴퓨터정보학부)
Abstract
In this paper, we consider a characterization of a Guard Sufficiency Set(GSS) in the hierarchy of simple polygons. we propose the diagonals of a arbitrary triangulation of a polygon as a GSS when guards see the diagonals with completely visibility and both sides of the diagonal. we show that this can be a GSS in convex polygons, unimodal polygons, spiral polygons but this can not be a GSS in star-shaped polygons, monotone polygons, completely external visible polygons.
