FYI, the Condorcet-Kemeny method correctly ranks M1 as second-most popular, and M2 as third-most popular. And it does so without the need for a "tie-breaker" adjustment. Richard Fobes On 10/27/2011 8:46 PM, capologist wrote: I recently conducted a vote under the Schwartz method. It produced

Hallo, as long as the used tie-breaking strategy guarantees that M1 is ranked ahead of M2, I see no problem. See section 5 of my paper: http://m-schulze.webhop.net/schulze1.pdf Markus Schulze Election-Methods mailing list - see http://electorama.com/em for list info

What makes a single-winner election method good? The primary consideration is that it gives good results. The clearest way to measure the quality of results is simulated voter utility, otherwise known as Bayesian Regret (BR). This is not the only consideration. But for this message, we'll discount
