Bucklin would've been a better choice to compare it to, but I chose to diffrentiate it because votes are withdrawn. IRV
was a bad chioce to then compare it too, I'll admit. In fact, an absolutely nonsensical one.<br><br>This actually seems to be one of the methods that a rash of people have come up with to try to satisfy a lot of criterion by voting strategically. The thing I thought was "well, what would you want to do in an approval election"?

However, I've yet to throw an
election at it that hasn't picked the Condercet winner, so maybe it does. Because it is vulnerable to circular ambiguities, however, it at least needs a tiebreaker, which I have yet to come up with. And there is probably a mess of criterion which I have missed. So maybe this is a lemon...<br><br>Oh well.<br><p>
