Dear Árpád Magosányi, here are the proposed statutory rules for the Schulze method: http://m-schulze.webhop.net/propstat.pdf If I understand you correctly, then you want to define the Schulze method in an axiomatic manner in your proposal. I don't think that this is a good idea. Markus Schulze

Hi! Sorry for top posting, But I believe I have found something nearing a suitable simple-word definition for Schulze. As this is what I desperately need, I offer it for scrutiny here: - The electors rank the candidates according to their preferences. - If there is a group of candidates all

I understand quite well Warren's point that for 2 and 3-candidate races, and with full ranking required, and equal ranking not allowed, then Approval (with the silly votes excluded) and ranked ballots can be encoded in the same number of bits. And yes, there is certainly an algorithm for turning a

To me all this sounds still a bit too complex for the referendum. I'd drop out all the criteria, Smith set etc. since the voters will not understand. There is also the risk that experts and opponents of the reform will sabotage the referendum by digging into the details (and thereby proving to

Dear Raph, Schulze and ranked pairs are the only methods that meet clone independence and the condorcet rule. Nope. River, too, of course, meets all three criteria... Does ranked pairs fail the Smith criterion? I would change B to If there is a group of candidates all preferred over
