2004-06-08 Thread Forest Simmons
If I understand correctly, Beat Path, Ranked Pairs, MinMax, and all of the other serious Condorcet methods are in agreement (except for the margins/wv debate) when there are only three candidates: if one of them beats each of the others pairwise, then that candidate is the winner. Otherwise, the

[EM] a similar method to weighted pairwise
