Total approval chain climbing

Total approval chain climbing (TACC) is a Condorcet completion method using an approval component, invented by Forest Simmons. In the three-candidate case it is equivalent to electing the candidate in the cycle who defeats the approval loser pairwise. The motivation is to reduce burial incentive.

It works as follows:

1. Sort the candidates by increasing total approval. 2. Starting with an empty "chain of candidates", consider each candidate in the above order. When the candidate defeats all candidates already in the chain, add her at the top of the chain. The last added candidate wins.

Notes

TACC and its variants are notable for always electing from the Banks set, a subset of the uncovered set and thus the Smith set.
