Hi Nicholas, I think that your basic method (page 2 of html version) is the same as
QLTD: http://www.mcdougall.org.uk/VM/ISSUE6/P4.HTM I say this because the multiplier is expressed in terms of ranking slots and a candidate is allowed to win with only part of a subsequent slot instead of only in increments of entire slots. So your full method is what I would call "QLTD elimination" because you repeatedly eliminate the QLTD loser. (Hopefully I haven't misunderstood the definition.) Elimination+Recalculation methods are bad for monotonicity because the way information can be used for or against candidates is usually not predictable. It would need to be quite clear how other candidates will fare when another candidate is eliminated. Participation is satisfied by simple point scoring methods. I doubt it is compatible with elimination+recalculations. The problem is that you need to guarantee each voter that information will only work in certain ways, but eliminations tend to have chaotic results. ______________________________ > De : Nicholas Buckner <nlbor...@gmail.com> >À : Kristofer Munsterhjelm <km_el...@lavabit.com> >Cc : election-methods@lists.electorama.com >Envoyé le : Samedi 9 juin 2012 4h04 >Objet : Re: [EM] Throwing my hat into the ring, possibly to get trampled > >Thank you for that information. I thought IIA referred to adding of >irrelevant alternatives, not removing them.

If there are only two candidates A and B and you add a new candidate C, and change the winner from A to B, then you could also take the new situation, and remove C from it, and thereby change the winner from B to A. You wrote originally "I developed an alternative method that takes the Independence of Irrelevant Alternatives path over the Condorcet path." Do you know that we don't have *any* serious rank methods that satisfy IIA? For example, STV doesn't satisfy it either.
