Hallo, > If you think that MAM is better than Schulze, then what criterion > (that we might care about) is met by MAM and not Schulze? The Schulze method (but not MAM or River) has the property that the winner is always chosen from that set X where the strongest win of a candidate outside set X against a candidate inside set X is as weak as possible. See section 4.8 of my paper: http://m-schulze.9mail.de/schulze1.pdf The above property of the Schulze method is also the reason why the worst pairwise defeat of the Schulze winner is usually weaker than the worst pairwise defeat of the MAM winner. Norman Petry, Jobst Heitzig, and Barry Wright confirmed this in their simulations. Therefore, the above property is not purely academic. Markus Schulze
