Hello Ken, Nice ideas. Correlation seems like a useful tool that could be applied also elsewhere than with Borda. It sure is more natural (and wider) than the normal clone definitions (unfortunately not as simple but of course so are peoples' opinions). Borda has some problems with

Ken, Does CIBR (like plain Borda) meet Participation? (a tall order). If not, does it meet Mono-raise (i.e. is it monotonic)? And a more general question: why do you think its better or more important to meet Symmetry than the Condorcet criterion? Chris Benham Election-methods mailing

First, a reposting for Jobst: CIBR stands for Correlated Instant Borda Runoff, and is a tweak of Baldwin to solve the clone problem. Individual ballots are scored according to the Borda count, and then all possible candidate pairs are ranked according to correlation. The Borda loser of

This looks promising. I like this kind of creativity. Three Questions: 1. Exactly how do you define correlation? 2. Do you re-calculate the correlations after each elimination? 3. What about clone triplets, quintuplets, etc.? Forest winmail.dat Election-methods mailing list - see
