Correction: When we count the ballots by Tideman and Schulze and
then choose that candidate of these 2 winners whose worst pairwise
defeat is smaller then this would violate independence from clones.
When we count the ballots by Tideman and Schulze and then choose
that candidate of these 2 winners who is pairwise prefered by more
voters then this would violate monotonicity.
