Hallo, in March 2003, Steve Eppley proposed a new tie-breaking strategy for Ranked Pairs. (Actually, as far as I remember correctly, this tie-breaking strategy has already been proposed in Sep. 2001 by Rob LeGrand to the Ranked Pairs mailing list.) Suppose that "pos[i]" is the position of candida

Dear Sampa, The exact result is that when there are n alternatives there are at most 2^(n-1) ballots which can form a single-peaked set, and the proof is a geometric argument using mathematical induction based on the number of ways to draw the single-peaked schedules in an nxn array of lattice

I did not explain what I wanted very clearly in my haste. Single-peakedness is a property of a collection of ballots with respect to an ordering of the alternatives.

If one can order the alternatives being voted on (candidates) on a linear scale so that all of the alternatives are "single peaked" (using ordinal ranking ballots) then if there are an odd number of voters the Condorcet method will always choose a winner.
