> Monotonicity is not a valid concept. I disagree. Tell me your prefer a method respecting the Secret Preferences Criterion (SPC) to a method respecting the Monotonicity Criterion. I like both and hope to find a way to reconcile them, aiming for scores, not for a winner.
Name: Score Monotonicity Criterion: SMC Definition: If an alternative X has score W, and the ballots are changed only by placing X in lower positions, without changing the relative position of other candidates, then X score W must be lower. Name: Secret Preferences Score Criterion: SPSC Application: Ranked ballots Definition: If alternative X has a score W, and some of the ballots are modified in their rankings below X, X must still have score W. I am working on it. St�phane Rouillon, Ing.
