Package: libmath-convexhull-monotonechain-perl (0.1-2 and others)

[ Source: libmath-convexhull-monotonechain-perl  ]

Perl module to calculate a convex hull using Andrew's monotone chain algorithm

Math::ConvexHull::MonotoneChain optionally exports a single function convex_hull which calculates the convex hull of the input points and returns it. Andrew's monotone chain convex hull algorithm constructs the convex hull of a set of 2-dimensional points in O(n*log(n)) time.

It does so by first sorting the points lexicographically (first by x-coordinate, and in case of a tie, by y-coordinate), and then constructing upper and lower hulls of the points in O(n) time. It should be somewhat faster than a plain Graham's scan (also O(n*log(n))) in practice since it avoids polar coordinates.
