Correlated Instant Borda Runoff
Correlated Instant Borda Runoff (CIBR) is a preferential voting system for single-winner elections, devised by Ken Kuhlman in May 2005 in order to reduce Borda's susceptability to clones.
Procedure
Candidates are scored according to the Borda count. The Borda loser of the most-correlated pair of candidates is eliminated. The process is repeated until only one candidate remains.
