Geometric Algorithms for Minimal Enclosing Disks in Strictly Convex Normed Planes

With the geometric background provided by Alonso, Martini, and Spirovaon the location of circumcenters of triangles in normed planes, we show the validity of the Elzinga--Hearn algorithm and the Shamos--Hoey algorithm for solving the minimal enclosing disk problem in strictly convex normed planes
