These methods successively eliminate candidates. For each round, the voter choice one candidate. If his favorite candidate is eliminated, his vote is properly transfered to the remaining candidates. Ties are tiebreakers by using the scoring method Borda.

• Alternative Vote: At each round, the worst candidate is eliminated. The vote can be transfered several times. For example, if the two favorites candidates have been eliminated, the vote is transfered to the third favorite candidate.
• Two Rounds Majority: In the second round, we only keep two candidates, who have the highest votes.
