Hi, The BPW (= "Beats Plurality Winner") method is a cyclebreaker proposed by Eivind Stensholt that he found to be resistant to burial. When there is a cycle among three candidates, you elect the one who defeats the first preference winner. (It's unknown how to define the method for more than three.) I coded it (incorrectly) and probably commented that I wasn't impressed.
However, having fixed the error, I feel the need to say I was wrong and that it is quite good at what it does. I tried it in three scenarios (aspectral, 1D, and center-heavy-nomination 1D) and in all three it either had the lowest burial rate for a Condorcet method, or (in one case) was beaten slightly by Condorcet//King of the Hill. The compromise and truncation incentives are pretty mediocre (i.e. highish) though. There's also a little pushover incentive. (I didn't allow compression due to the nature of the method.) I'm planning to compile some stats from my sim to put in an Excel file that people can download and look through on their own... That way I won't have to type everything up and people can sort as they wish and such. There is probably also a need to distribute method source code so that if I have implemented a method incorrectly (as in this case) it may be spotted someday...
