As stated in https://numpy.org/doc/stable/reference/generated/numpy.sort.html, NumPy replaces quicksort with introsort in 1.17, which is
O(n log(n)), just like stablesort. This is the default algorithm, i.e. used whennp.sort(..., kind=None).Since Lmo generally deals with i.i.d. samples, stablesort also has no practical advantage over introsort, hence making it a better default for Lmo.
