Webbthus, if we directly apply the randomized incremental construction for abstract Voronoi diagrams [16] we get an O(n2 logn)-time algorithm, and this is not easy to overcome (see [6]). When clusters are crossing, their bisectors are disconnected curves [20], and thus, they do not satisfy the basic axioms of abstract Voronoi diagrams.
