Query: Improving Ranking Quality and Fairness in Swiss-System Chess Tournaments   The International Chess Federation (FIDE) imposes a voluminous and complex
set of player pairing criteria in Swiss-system chess tournaments and endorses
computer programs that are able to calculate the prescribed pairings. The
purpose of these formalities is to ensure that players are paired fairly during
the tournament and that the final ranking corresponds to the players' true
strength order. We contest the official FIDE player pairing routine by
presenting alternative pairing rules. These can be enforced by computing
maximum weight matchings in a carefully designed graph. We demonstrate by
extensive experiments that a tournament format using our mechanism 1) yields
fairer pairings in the rounds of the tournament and 2) produces a final ranking
that reflects the players' true strengths better than the state-of-the-art FIDE
pairing system.
