finitions of "completion method" and "aggregate method"</div><div dir="auto"><br></div></div><pre>Hi folks,
There are two new articles on electowiki that may not make sense to
those of you who are are intimately familiar with election-methods
jargon:
"aggregate method":
<a href="https://electowiki.org/wiki/Aggregate_method">https://electowiki.org/wiki/Aggregate_method</a>
"completion method"
<a href="https://electowiki.org/wiki/Completion_method">https://electowiki.org/wiki/Completion_method</a>
An "aggregate method" is jargon I made up to describe the methods that
we've been describing all along on this mailing list (e.g. the
"Smith//Condorcet" method was popular on the EM list[1]).
[1]: <a href="http://lists.electorama.com/pipermail/election-methods-electorama.com/1996-August/065995.html">http://lists.electorama.com/pipermail/election-methods-electorama.com/1996-August/065995.html</a>
What I mean by "aggregate method" is a method where a series of
methods (Copeland, Smith, etc) are chained together. Then the "winner"
(or "winners") pop out at the end of the chain.
What I mean by "completion method" is the method at the end of the
chain in an "aggregate method".
Am I using those terms the way that people who make a living
researching/studying this stuff use those terms? I don't want to
redefine terms, but if no one agrees on what "completion method" means
(or has a really sloppy definition of it, or just uses the term
without knowing what it means to sound smart), then I don't feel bad
about redefining the term. Regardless, I would really appreciate some
help coming up with good definitions.
Thanks
Rob
