Pairwise Sorted Approval
Pairwise Sorted Approval is the simplest of a class of Pairwise Sorted Methods.
A voter ranks candidates, and specifies approval, either by using an Approval Cutoff or by ranking above and below a fixed approval cutoff rank.
To determine the winner,
- sorted candidates in descending order of approval.
- For each candidate, move it higher in the list as long as it pairwise beats the next-higher candidate, and only after all candidates above it have moved upward as far as they can.
This procedure can be used to produce a social ordering. It finds the same winner as Definite Majority Choice.
