Noting that a series of mechanical rules created for pairing and placement of judges at the National Debate Tournament (NDT) may be useful in developing a computer program to pair tournaments, this paper focuses on the methods used to pair rounds at the NDT and also looks at some pairing options frequently employed by other debate tournaments. The first section of the paper describes the pairings and judge assignments for preset debate rounds. The second section describes the procedures for powermatching in the preliminary rounds, including odd and even round pairings and pairings for the eighth or final round, and judge placement for these rounds. The third section describes the pairings and judge placements for the elimination rounds. (HTH)
