## Abstract We experimentally evaluate sequential and distributed implementations of an approximation partitioning algorithm by Kalpakis and Sherman for the __Geometric Steiner Minimum Tree Problem (GSMT)__ in __R^d^__ for __d__ = 2,3. Our implementations incorporate an improved method for combinin
