I do not know what "clone-independent" means (perhaps I should by now). No rank ballot system can meet IIA while electing an unanimous preferred candidate and having no dictator. (That doesn't mean Schulze is as bad as IRV, though, only that "perfection" cannot be attained.) Clone-independence means that if one adds or removes candidates from a set that all voters vote next to each other (but not necessarily in the same order), that shouldn't cause someone in the set to lose if someone in the set won before the modification, and nor should it cause someone in the set to win if a candidate outside the set won before the modification. Intuitively, it means that a party shouldn't lose (or win) merely by splitting. Election-Methods mailing list - see http://electorama.com/em for list info

[EM] Schulze Method
Hallo, I have uploaded a new version of my paper "A New Monotonic, Clone-Independent, ...": http://m-schulze.webhop.net/schulze1.pdf I have shortened my paper from 167 pages to 64 pages. The new version is simpler and more stringent than the old version (because, in the new version, I use one and only one heuristic for the Schulze method). The proofs are simpler because I moved the random ballot tie-breaker from section 2 to section 5. Markus Schulze Election-Methods mailing list - see http://electorama.com/em for list info
