Participants, I've had a request from John Hodges, who used to subscribe and contribute to EM.
> could you ask the EM folk for an evaluation of the properties of CNTT,QLTD? That stands for "Condorcet(Net) Top Tier, Quota-Limited Trickle-Down", which means "order the candidates using the QLTD method and then elect the highest-ordered member of the Smith set". QLTD is a Bucklin-like method invented by Woodall. Quoting from one of his papers: > My first serious attempt to find a rule that would rival AV resulted in what I call Quota-Limited Trickle-Down (QLTD). Although this has now been superseded by DAC, I describe it here because it is simpler. One starts by crediting every candidate with all their first-preference votes. If no candidate exceeds the quota (of half the number of votes cast), then one gradually adds in the second-preference votes, then the third-preference votes, and so on, until some candidate reaches the quota. For example, it may be that if one credits every candidate with all their first-preference votes, all their second-preference votes and 0.53 times their number of third-preference votes, then exactly one candidate is brought up to the quota; that candidate is then declared elected. > > > The method fails both Clone-Winner and Clone-Loser. Methods like CNTT,DSC and CNTT,DAC seem to be better in terms of criterion compliances,but John thinks that CNTT,QLTD might have compensating practical advantages.
