* '''[[Schulze method|Schulze]]''' with several reformulations/variations, including '''Schwartz Sequential Dropping (SSD)''' and '''Cloneproof Schwartz Sequential Dropping (CSSD)'''<sup>1</sup>
* '''[[Approval-Condorcet Hybrids]]''', such as '''[[Definite Majority Choice]]''', use an [[Approval Cutoff]] to augment the Condorcet pair wise array. Many believe that such a method would make a good first-round public proposal.
*'''[[Smith//Score]]''' chooses the candidate with the highest summed or average score in the Smith Set. Condorcet//Score chooses the Score winner when no Condorcet winner exists. (ThisThese can only be done with rated ballots, or with ranked ballots modified to include approval thresholds).
