The min-max voronoi diagram of polygons and applications in VLSI manufacturing

Abstract

We study the min-max Voronoi diagram of a set S of polygonal objects, a generalization of Voronoi diagrams based on the maximum distance between a point and a polygon. We show that the min-max Voronoi diagram is equivalent to the Voronoi diagram under the Haus-dorff distance function. We investigate the combinatorial properties of this diagram and give improved combinatorial bounds and algorithms. As a byproduct we introduce the min-max hull which relates to the min-max Voronoi diagram in the way a convex hull relates to the ordinary Voronoi diagram. © Springer-Verlag Berlin Heidelberg 2002.
