On the construction of abstract Voronoi diagrams

K Mehlhorn, S Meiser, C Ó'Dúnlaing - STACS 90: 7th Annual Symposium …, 1990 - Springer
We show that the abstract Voronoi diagram of n sites in the plane can be constructed in time
O (n log n) by a randomized algorithm. This yields an alternative, but simpler, O (n log n) …
