From Ing. Milan Selingr:
Pairing program fills the gap between the programs for the PC, which allows drawing called Swiss system tournament. It was proposed for tournaments in badminton, but it is essentially applicable in other sports, which is played on points in a set (table tennis, squash, tennis, billiards, ). That is basically unusable in tournaments, which require that all participants played the same number of matches and which is usually not known in advance the order of performance of players. It is therefore a great help in organizing tournaments and holiday pupil categories.
