My O(n^2) method would be pretty transparent, I think; it would just get<br>
unwieldy very fast.<br>
<br>
First you let each person represent a candidate, and then, for each<br>
person, you have that person ask "do I beat A, B, C..." in turn. This<br>
gives the number of candidates that candidate beats, i.e. the Copeland<br>
score.<br>
<br>
Let there be a dividing line: everybody to the right (say) of that line<br>
is in the provisional Smith set, everybody to the left is not. Move the<br>
Copeland winner to the right of the line.<br>
<br>
Then ask each other candidate if he beats the first member, second<br>
member, etc. of that set. If yes, move him up to the other side of the<br>
line. If anyone was moved to the right of the line as part of this<br>
round, restart from the first candidate to the left of the line once<br>
you've asked all of them; otherwise, the process is done and the<br>
candidates on the right constitute the Smith set.<br>
