      I am looking for a numerical example where STAR voting fails Condorcet Winner criterion.

          @masiarek yes, B is the Condorcet winner and fails to be elected by STAR, so this example demonstrates that STAR is not Condorcet compliant. In this example we find

          A>B: 10-9-2=-1
          A>C: 10-9-2=-1
          B>C: 10-9+2=+3

          Therefore the digraph is

          A-->B<--C<--A

          and B is the Condorcet winner.

          score-stratified-condorcet [10] cardinal-condorcet [9] ranked-condorcet [8] score [7] approval [6] ranked-bucklin [5] star [4] ranked-irv [3] ranked-borda [2] for-against [1] distribute [0] choose-one [0]
