About:
Condorcet with Dual Dropping is a ranking system for deciding single or multi-winner contests (elections) using voted preference (or approval) ballot list or pairwise tally matrix. It computes the Cloneproof Schwartz Sequential Dropping (CSSD) and Tideman's Ranked Pair (RP) results for each contest round, and selects the combined CSSD and RP outcome with the lowest overall dropping cost. There are options to compute just the CSSD, RP, or Minimum Dropping Cost outcome, various optional pair rank and winner tie-breakers, and alternative measures of dropping cost (winning votes and/or margin). It comes as a console program and CGI executable.

Release focus: Minor bugfixes

Changes:
A problem with the findCycles subroutine has been fixed. The $CGI_in variable is set in the script to enable execution via an HTML form. A sample HTML form is included. The --HTML_out command outputs HTML. The --show_TBR command displays the TieBreak Rank file contents. The Graph module is included in the lib subdirectory.
