[EM] Empirical data on cycles

2005-09-02 Thread Andrew Myers
I thought the folks on this list would find it interesting to see some actual empirical data on how often cycles happen. I have data on 99 CIVS elections that have been run in which more than 10 voters participated (max was 1749) and in which there were at least three candidates (max was 72). These

[EM] Citation for immunity to strategic voting?

2005-09-02 Thread Andrew Myers
Hi all, I'm writing a short paper on secure implementations of Condorcet voting. I would like to claim that Condorcet methods are immune to strategic voting when there is a Condorcet winner (that is, voters cannot improve the election result from their perspective by voting insincerely). Is there

Hi Dave, The moderation of the Condorcet mailing list is off-topic for the EM list. As you are well aware, I have a very open policy when it comes to the EM list...it's pretty much a free-for-all, because this list was founded by a group of people who were shouted off a CVD-operated list for not
