[EM] (3) EM: VoteFair/Kemeny-Young: Steve's 3rd dialogue with Kristofer and Richard

[Kevin Venzke]

MAM, River, and Beatpath(wv) are a lot closer to each other than any is to Kemeny-Young. Those three satisfy basically all the same criteria. The "MAM" criterion (whatever it's actually called) may have some small value missing from River or Beatpath/Schulze, but even by that measure these two are nearly as good. Kemeny is really a different ballpark.

S:  Is MAMsignificantly different from Kemeny-Young/VoteFair?  Might VoteFair popularity ranking also MaximizeAffirmed Majorities as does MAM? If so, perhaps JamesGreen-Armytage’s following findings withregard to MAM might equal characterize VoteFair:The following part of JGA’s analysis of the different preferred resultswhen using the following different pairwise calculations to discover the winner,her reports that: “Judging from who beats whom, max. length, mean length, or sumofdefeats, we get MAM> River+ > Beatpath.Judging from number of defeats (= Copeland score), we geteither MAM >River+ > Beatpathor MAM >Beatpath > River+.”  [This is quotation from page 8 of JGA’s post 11years ago:From: James Green-Armytage
