2-Approximation for the Min. k-Enclosing Geodesic Disc in a Simple Polygon

I will present the algorithm I am currently working on that uses random sampling and a combination of polygon decomposition and k-levels to get a 2-approximation algorithm for the min enclosing geodesic disc of k points in simple polygons. The polygon has m vertices total, r reflex vertices, and the set of points S that our k points is to be chosen from has size n. After O(m+(n + r)\log(r)) preprocessing, the runtime of the current approach is O((n^{11/7}\log^2(n)+nr)\log(r)).
