A winner set is a set of candidates equal in size to the number of seats to be filled. When there is only one seat to be filled, it is customary to refer to a winner set simply as a candidate.
Winner sets feature prominently in discussions on who to elect in multi-winner bloc voting methods and proportional representation methods. Properties such as Proportionality for Solid Coalitions offer suggestions as to who should be in the winning winner set, with combinatorics and set theory featuring prominently in the discussion.
Sequential proportional voting methods elect a winner set one candidate at a time, while optimal proportional methods involve evaluating every possible winner set. In the single-winner case, there are only [number of candidates] winner sets, but there are exponentially more winner sets with more winners. For example, with 10 candidates and 3 winners, there are 120 possible winner sets.
