Thank you Forest, Colin, and Kristofer for answering my question about
how to manually identify the Smith set.
I now better understand how to do this on paper.
However, I'm still uncertain how it could be done in a public setting
such as on stage in a school auditorium, with an audience watching to
ensure the process is fair. (And creating a video of the process.)
Doing calculations on paper would not be acceptable because
non-math-savvy viewers would regard it as untrustworthy "magic."
Forest's idea of pulling out a calculator and doing matrix calculations
is very clever, but of course that's not the kind of "manual" process
that would be meaningful to an audience.
What I think can be followed is to do the pairwise counting with people
who are "pairwise counters." Each one focuses on just one pair of
candidates. Perhaps a video screen behind each person can show the
ballot being looked at and the screen can show the current pairwise
counts for that pair.
At the end of this process perhaps each pairwise counter can use a
felt-tip pen to write a sign that say something like:
Alder
wins over
Cedar
But what would be a good audience-visible process -- using people on the
stage -- that converts these win-loss signs into the Smith set?
Your answers use the word "sort." How could this sorting process be
represented using the signs and some people on a stage?
Of course when there's a Condorcet winner, finding the candidate who has
a win count equal to one minus the number of candidates is simple.
But what happens when there is no Condorcet winner?
It would be acceptable for an announcer to say things like "If Alder won
over your other pairwise candidate, please hold your sign up high,
otherwise keep your sign low. ... I see that Alder has 4 pairwise wins."
Such wins/losses can be written on different signs that say something like:
5 wins for Alder
But what can be shown as an action for a non-simple case, such as the
following one in Wikipedia?
5 wins for A
5 wins for D
4 wins for G
3.5 wins for C
2.5 wins for F
1 win for B
0 wins for E
(Half indicates a tie.)
So, does anyone have a suggestion for how some interactions on stage can
clearly -- and hopefully simply -- show how to resolve this more complex
kind of situation?
