WebDec 31, 1996 · The second question is answered in the affirmative by using a slight modification of an O(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. WebThe greedy projection triangulation algorithm is an algorithm for rapid triangulation of the original point cloud. This algorithm assumes smooth curved surface, and the point cloud density is uniform, and the surface is smoothed and holes in the triangularization.

WebMar 21, 2024 · Greedy is an algorithmic paradigm that builds up a solution piece by piece, always choosing the next piece that offers the most obvious and immediate benefit. So the problems where choosing locally optimal also leads to global solution are the best fit for Greedy. For example consider the Fractional Knapsack Problem. 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 ...
