Election:2003 Debian Project Leader

From Electowiki

Actual results of the 2003 Debian Project Leader elections. See http://www.debian.org/vote/2003/vote_0001 . The Debian Project uses the Schulze method, but Instant runoff voting results are also provided for comparison purposes. A detailed discussion of these results is also available, written long ago before this program was released. See talk page for discussion about conversion of ranked ballots to range ballots. An approval voting tally is also provided, which assumes all candidates better than NOTA are approved, and all candidates equal to or below are not approved. The approval result is admittedly dubious, since it's not obvious the voters would have actually voted that way.

Schulze Method(wv-mod)

The winner is Michlmayr.

Detailed Results

The results below were calculated using the Beatpath algorithm for Schulze(wv-mod). This is done first calculating the pairwise results, then creating two matrices of winning votes (with negative opponents' votes in event of a loss) and margin of victory. It then calculates two Beatpath matricies, which is a matrix of the better of a direct victory or a transitive victory. The transitive victory strength of x over z is the weakest victory of x over y and y over z. The winning votes matrix is used as a primary source, iwith the margins matrix used as a tiebreaker. The winner is the candidate for which there are no beatpath defeats.
