Farthest first traversal

A farthest-first traversal is a sequence of points in a compact metric space, with each point appearing at most once. If the space is finite, each point appears exactly once, and the traversal is a permutation of all of the points in the space. The first point of the sequence may be any point in the space. Each point p after … See more In computational geometry, the farthest-first traversal of a compact metric space is a sequence of points in the space, where the first point is selected arbitrarily and each successive point is as far as possible from the set of … See more Rosenkrantz, Stearns & Lewis (1977) used the farthest-first traversal to define the farthest-insertion heuristic for the travelling salesman problem See more • Lloyd's algorithm, a different method for generating evenly spaced points in geometric spaces See more Greedy exact algorithm The farthest-first traversal of a finite point set may be computed by a greedy algorithm that … See more WebFarthest-first traversal; Metadata.
