Abstract

We present a fixed-parameter algorithm for the Minimum Convex Partition and the Minimum Weight Convex Partition problem. The algorithm is based on techniques developed for the Minimum Weight Triangulation problem. On a set P of n points the algorithm runs in O(2^kk^4n^3+nlogn) time. The parameter k is the number of points in P lying in the interior of the convex hull of P.
