Young's method

From electowiki

Young's method is a Condorcet method that elects the candidate that can be made into a Condorcet winner by ignoring as few ballots as possible. It was devised by H. P. Young in 1977.[1]

Determining the Young winner is complete for parallel access to NP,[2] and thus NP-hard. The method is not summable. In addition, it is monotone but fails the Smith criterion.[3]
