http://condorcet-dd.sourceforge.net/ Called Dual Dropping, it is a minimum dropping cost based combination of two Condorcet methods, Tideman's Ranked Pairs and Cloneproof Schwartz Sequential Dropping (can also execute RP or CSSD separately). It is actually two scripts, the optional first script converts a preference ballot list into a Condorcet square (a matrix of one on one competition vote totals) which is then utilized as the input for the script that determines the winner(s). It can be used as a ranking for system for anything that generates preference ballots. It is usefull for organization/club voting whenever there are three or more choices.
