The post-office problem for fuzzy point sets

F. Aurenhammer, G. Stoeckl, and E. Welzl

Abstract:

The post-office problem for $n$ point sites in the plane (determine which site is closest to a later specified query point) is generalized to the situation when the residence of each site is uncertain and it is described via uniform distribution within a disk. Two probabilistic concepts of neighborhood, - expected closest site and probably closest site - are discussed and the resulting Voronoi diagrams are investigated from a combinatorial and computational point of view.
