摘要: It is shown that the order-k Voronoi diagram of n sites with additive weights in plane has at most (4kź2)(nźk) vertices, (6kź3)(nźk) edges, and (2kź1)(nźitk) + 1 regions. These bounds are approximately same as ones known for unweighted diagrams. Furthermore, tight upper on number edges vertices given case every weighted site a nonempty region order-1 diagram. The proof based new algorithm construction these diagrams which generalizes plane-sweep developed by Steven Fortune. time-complexityO(k2n logn) space-complexityO(kn). only nontrivial constructing order-kc withadditive weights. fairly simple practical interest also special sites.
