The Second Geometric Optimization Challenge is part of CG Week in Zurich, Switzerland, June 22-26, 2020. The task is to solve the Minimum Convex Partition Problem, which asks for a set of edges connecting a given set of points which partitions the convex hull of the points into the minimum number of convex regions.
