摘要: Chew and Dobkin et. al. have shown that the Delaunay triangulation its variants are sparse approximations of complete graph, in shortest distance between two sites within is bounded by a constant multiple their Euclidean separation. In this paper, we show other classical algorithms, such as greedy triangulation, more notably, minimum weight also approximate graph sense. We design an algorithm for constructing extremely (nontriangular) planar graphs graph.
