Webthe Weak Greedy Algorithm with parameter b. It is interesting to compare the rates of convergence of the PGA and the Orthogonal Greedy Algorithm (OGA). We now give a brief definition of the OGA. We define fo 0:= f, Go 0(f,D) = 0 and for m ≥ 1 we inductively define Go m(f,D) to be the orthogonal projection of f onto the span of g(fo 0 ... Web2 days ago · April 12, 2024 5:06 am ET.

The method works by maintaining a list of points from which the mesh can begrown ("fringe" points) and extending it until all possible points areconnected. It can deal with unorganized points, coming from one or multiplescans, and having multiple connected parts.
