Lomax says: Nevertheless, Warren has a point. He states conclusion based on thin evidence, yes. But he does this when there, essentially, is *no* other evidence. I reply: No, not really. There is evidence that no one here proposes Condorcet without equal rankings. Strong evidence, in fact.

ok, sorry for my dimness here. Thanks to Benham and Venzke we now have two readable definitions of SFC: Benham-SFC: "If more than half the voters vote X over Y and it is possible to complete truncated ballots in a way to make X the CW, then Y must not win." Venzke-SFC: "If more than half of the

Jobst, I'm still digesting your new method. It is starting to make sense to me. It is extremely creative and ingenious, in my opinion. I just hope that we haven't overlooked any subtle logical error. I have one question, though. If best strategy is to report true utilities, then what do you

[EM] A more efficient strategy-free ratings-based method than Hay voting

2007-02-12 Thread Jobst Heitzig
Dear friends, Hay voting was supposedly the first known method under which it is always optimal (as judged from expected utility) to vote sincere ratings (i.e. ratings proportional to true utility). However, it seems that it is a rather inefficient method (as judged from total expected utility)
