Complex sentence: Minty cube have shown bad behavior of path-following algorithms for linear optimization, in that the central path comes arbitrarily close to each of the corners of a cube; this is surprising because such algorithms have polynomial-time complexity for linear optimization.
Split into simpler sentences: Minty cube have shown bad behavior of path-following algorithms for linear optimization, in that the central path comes arbitrarily close to each of the corners of a cube. This vertex-stalking behavior is surprising, because such algorithms have polynomial-time complexity for linear optimization.
