Greedy triangulation algorithm
WebMay 22, 1989 · The greedy triangulation of a finite planar point set is obtained by repeatedly inserting a shortest diagonal that does not cross those already in the plane. … WebTriangulation is performed locally, by projecting the local neighborhood of a point along the point’s normal, and connecting unconnected points. Thus, the following …

WebApr 15, 2001 · The greedy triangulation (GT) is the triangulation defined procedurally by a greedy algorithm that starts by sorting all n 2 pairs of points by lengths of the segments connecting each pair. The algorithm then builds the GT one edge at a time by examining each edge e in increasing order of length: adding edge e if e crosses no previously added ...

Geometric software by Darcy Quesnel: Randomized parallel 3D convex hull, with documentation; 2D Delaunay triangulation, Voronoi diagram, and convex hull (requires … WebA common approach for finding good decompositions is iteratively executing a greedy triangulation algorithm (e.g. minfill) with randomized tie-breaking. However, utilizing a stochastic algorithm as part of the inference task introduces a new problem — namely, deciding how long the stochastic algorithm should be allowed to execute before ...
WebJun 17, 1987 · The second question is answered in the affirmative by using a slight modification of anO(n log n) algorithm for the greedy triangulation. We also derive some other interesting results. For example, we show that a constant-factor approximation of the minimum weight convex partition can be obtained within the same time bounds.
