Line 108:
When criterion #2 is used, this is equivalent to requiring that the winner always comes from the [[CDTT|Condorcet (doubly-augmented gross) top tier]] or [[CDTT]].
The most popular method which satisfies these properties is the [[Schulze method]].
<br />
== Notes ==
== [[ISDA]] implies several of the criteria mentioned above. When there is a mutual majority and a minority with a preference among the mutual majority's preferred candidates, the ISDA-based reasoning for deciding who to elect is to eliminate everyone not in the mutual majority, check if there is a new mutual majority set, and then repeat. Taking the above example ==
<br />
: 31 A > B > C
: 29 B > C > A
: 40 C > B > A
== There is a mutual majority of 69% of voters for B and C, so by ISDA, A can be eliminated. Then, there is a majority who put B as their 1st choice, and because ISDA implies the majority criterion, B wins. ==
== A majority is a Droop quota in the single-winner case. ==
