It finds whether there is a CW, although that's not reflected in the stats. So it would be easy to make the simulation ignore cases where there is a CW, or where there isn't. Do you suppose such results would be interesting? > "It's surely a fluke that "Two Evils" outperforms "Zero-Info" here. > "I have to doubt that random information could be better than none at > "all. > > It comes as no surprise that zero-info performed about as well as > Schulze in terms of average utility.

I agree with that.

I don't quite understand why you say this last part. Thanks for the reply. Kevin Venzke [EMAIL PROTECTED] Yahoo! Mail : votre e-mail personnel et gratuit qui vous suit partout ! Créez votre Yahoo!
