WebAlgorithms, 4th Edition ... • Sort points by polar angle with p. • Consider points in order, and discard unless that would create a ccw turn. 2 Graham scan p WebGraham Scan. A Java implementation of the Graham Scan algorithm to find the convex hull of a set of points. How to use it. The implementation is pretty straight forward: everything resides in a single class ().Simply copy the class in your project, and invoke either GrahamScan#getConvexHull(int[], int[]):

You could also implement a function generating instances where you know the optimal solution (by construction). But it will be more biased. – sascha. Sep 17, 2016 at 22:16. 1.
