Deletion in abstract Voronoi diagrams in expected linear time and related problems

K Junginger, E Papadopoulou - arXiv preprint arXiv:1803.05372, 2018 - arxiv.org
Updating an abstract Voronoi diagram after deletion of one site in linear time has been a
well-known open problem; similarly, for concrete Voronoi diagrams of non-point sites. In this …

A randomized divide and conquer algorithm for higher-order abstract Voronoi diagrams

C Bohler, CH Liu, E Papadopoulou… - Computational …, 2016 - Elsevier
Given a set of n sites in the plane, their order-k Voronoi diagram partitions the plane into
regions such that all points within one region have the same k nearest sites. The order-k …
