Condorcet with Dual Dropping
A preference or approval ballot vote tabulation and ranking system for deciding single or multi-winner contests (elections). Computes the Schwartz Sequential Dropping (SSD) and Tideman's Ranked Pair (RP) results for each contest round and selects the combined SSD and RP contest outcome with the lowest overall dropping cost. It has options to compute just the SSD or RP outcome, various optional tie-breakers, and alternative measures of dropping cost (winning votes and/or margin).
