What is the problem with the definition of clone? There seem to be
two definitions, if I look at Wikipedia. One is that the two
candidates are identical. This would require equal rating in Range,
for example, and Range would clearly pass ICC. The other is that the
candidates are only ranked identically,
I comment:
The definition that I heard was that the clones are consecutively-rankeed
(not necessarily in the same order) by everyone. In other words, it's a set
of candidates between whom no one ranks anyone else.
It's been a long time since I discussed this, but definilng ICC is a problem
if it's based on preferences. Then we have to decide how people's voting is
constrained. Do they try to maximize ltheir utility expectation, for
instance?
I've heard peference-based definitions that were vague because they
specified no such constraints. Preference-based definitions of IIAC have
that problem too. But I don't object to preference-based criteria, if
they're well defined. For instance, my defensive strategy criteria are
preference-based.
But the only satisfactory ICC definition that I know of isn't preference
based. It's votes-only. It's the only one that I've heard agreement on.
Because of the modem-shutoff problem, I'd better quit here.
