Center node: "a new approach to output sensitive voronoi diagrams and delaunay triangulations"
  Abstract: We describe a new algorithm for computing the Voronoi diagram of a set of $n$ points in constant-dimensional Euclidean space. #R##N#The running time of our algorithm is $O(f \log n \log \Delta)$ where $f$ is the output complexity of the Voronoi diagram and $\Delta$ is the spread of the input, the ratio of largest to smallest pairwise distances. #R##N#Despite the simplicity of the algorithm and its analysis, it improves on the state of the art for all inputs with polynomial spread and near-linear output size. #R##N#The key idea is to first build the Voronoi diagram of a superset of the input points using ideas from Voronoi refinement mesh generation. #R##N#Then, the extra points are removed in a straightforward way that allows the total work to be bounded in terms of the output complexity, yielding the output sensitive bound. #R##N#The removal only involves local flips and is inspired by kinetic data structures.
