[[Condorcet methods]] require the resolution of [[cycles]]. Typically, this is done by ignoring "weak" pairwise defeats in favor of "strong" ones. The metric used to distinguish these is called '''defeat strength'''.
* '''winning votes''': Defeat strength = votes for W>L
* '''margins''': Defeat strength = (votes for W>L) - (votes for L>W)
* '''relative margins''': Defeat strength = margin ÷ (votes for W≠L)
Less common measures:
====== Approval opposition ======
'''Approval opposition''' or '''AO''' is a measure of defeat strength for [[Condorcet method|Condorcet methods]]. It is equivalent to using [[Cardinal pairwise|approval-weighted pairwise]].
