Randomization Yields Simple $O(n \log^{\star} n)$ Algorithms for Difficult $\Omega(n)$ Problems
Résumé
We use here the results on the influence graph to adapt them for particular cases where additional information is available. In some cases, it is possible to improve the expected randomized complexity of algorithms from O(n log n) to O(n log* n). This technique applies in the following applications: triangulation of a simple polygon, skeleton of a simple polygon, Delaunay triangulation of points knowing the EMST (euclidean minimum spanning tree).
