Line 13:
MMPO's choice rule can be regarded as a kind of social optimization: The election of the candidate to whom fewest people prefer another. That choice rule can be offered as a standard in and of itself.
Minmax may be indecisive, particularly for small electorates, because it only considers a single pairwise contest for each candidate. This tendency to tie can be broken by a ''leximax'' tiebreaker: if two or more candidates have the same strength greatest defeat, then elect the one that has the least next-greatest defeat. Repeat as needed.
Minmax with a leximax tiebreaker is sometimes called '''Ext-Minmax''' on the [[election-methods mailing list]]. It is the standard tiebreaker for MMPO as defined by Mike Ossipoff.
