As the author mentioned, he has done some search on that topic too and has found nothing. So, either I would have to trust his word (and his non-public proof) that it works or I would have to prove it myself. Besides that he says it's based on bubble sort, which is known for its speed. So I would have had to write in C in order to see if the speed would be acceptable and would still be without any proof that it always works correctly. Regards, Alexander Holler
