46. Unfortunately, at the moment we cannot extend our investigations to more settings than five. This is because of the memory requirements of the program and speed of the machine. Further, we cannot be 100 % certain that the algorithm reaches the global minimum. Still, the program is constructed in such a way that it never gives too low values for v crit. Thus, we are always on the safe side with our claims of nonclassicality.
