Bottleneck Partial-Matching Voronoi Diagrams and Applications (1405.0900v2)
Published 5 May 2014 in cs.CG
Abstract: Given two point sets in the plane, we study the minimization of the bottleneck distance between a point set B and an equally-sized subset of a point set A under translations. We relate this problem to a Voronoi-type diagram and derive polynomial bounds for its complexity that are optimal in the size of A. We devise efficient algorithms for the construction of such a diagram and its lexicographic variant, which generalize to higher dimensions. We use the diagram to find an optimal bottleneck matching under translations, to compute a connecting path of minimum bottleneck cost between two positions of B, and to determine the maximum bottleneck cost in a convex polygon.
