Markus, you and your beatpath just have to step aside because MIKE
OSSIPOFF is clearly the most knowledgeable expert here.
The Schulze method is analyzed here:
http://m-schulze.webhop.net/schulze1.pdf
The Schulze method satisfies anonymity, neutrality,
homogeneity, resolvability, Pareto, reversal symmetry,
mono-raise, mono-add-plump, Condorcet, Smith,
Schwartz, independence of clones, and independence of
Smith-dominated alternatives. It satisfies Woodall's
CDTT criterion, Woodall's plurality criterion,
Ossipoff's SFC, and Ossipoff's SDSC.
The Schulze method has been published several times
in scientific journals and in scientific books.
The Schulze method is currently used by more than
50 organizations with more than 70,000 members in
total.
in all seriousness, Markus, everything you said above is true, and i am
fully convinced that the Schulze method *is* the best method from a POV
of best inhibiting or resisting voting strategies that make use of
throwing a clean Condorcet race into a cycle.
but this statement:
Of all Condorcet methods, that are currently discussed,
the Schulze method is that method that has the best
chances of getting adopted.
i disagree with, at least as far as getting adopted for governmental
elections. it is much harder to explain than either minmax or
ranked-pairs. and, if my understanding is correct, Schulze,
ranked-pairs, and minimax all pick the same winner in the case where
there are 3 candidates in the Smith set, is that not so? so, as
unlikely as a Condorcet cycle is (and that's the big sale to make to
voters and legislators about adopting Condorcet, especially after they
rejected IRV as being "too complicated"), it's even more unlikely that,
if a cycle ever happens, that more than 3 candidates will be in the
cycle. i don't think it will *ever* happen in a governmental election
that a larger Smith set occurs and Schulze will be needed to select the
correct winner when ranked-pairs fails to do so.
"The Perfect is the enemy of the Good" and it's so much more important
to get a Condorcet method adopted than to "go for broke" and get the
best Condorcet method adopted since there will be effectively no
difference in the outcomes.
