Maybe it is because I am not familiar with this voting system, but my initial understanding of the description of the algorithm does not match up with the test. It says 'In case of a tie for least, remove all of the tying candidates.', but if I look at the test, every party is listed for every voter, which would mean they all tie for least votes. Yet :ind is expected to be the winner.
I guess only the first votes are compared?
Anyway I found the description to be a little too vague on that point.
