Hallo, I remember that we discussed the following criterion at this mailing list. Unfortunately, I forgot the name of this criterion. Could someone please tell me the name of this criterion? Suppose M is the number of candidates. Suppose there is a k with 2 <= k <= (M-1) such that candidate A wins every sub-election between candidate A and (k-1) other candidates. Then candidate A should also be the overall winner. Markus Schulze
