Smith//STAR

[cfrank]

Simply restrict to the Smith set, then perform STAR. Does anybody know about the formal properties of this system?

Also, I find this construct interesting:

@cfrank It would still fail independence of clones.

The EM mailing list has a lot of discussions about Condorcet methods including ones which elect a winner from the Landau set.

@toby-pereira I see, so the issue is that STAR fails independence of clones due to the majoritarian runoff. But the simple Smith(or Landau)//Score(or Approval) should not. Are there well-known issues with that?

Do you know how the Landau and Schwartz sets are related? For example, is it known whether they always have a nonempty intersection?

@cfrank I'm not really the best person to ask about these methods probably. I don't know off the top of my head what criteria they pass/fail. However, the Landau set and others are discussed more here.
