Competition system arrangement method
The number of rounds in the competition is roughly twice the number of rounds required for the knockout round, and the odd number is taken. For example, the 60-player knockout is six rounds, which is twice as much as 12, and then accept the odd number of 1 1 or 13 rounds. 1 round randomly draw lots for matching, and then rearrange each round according to the results of the previous round. In principle, high scores compete with high scores and low scores compete with low scores.
It is suggested to use Swiss circle system, that is, point arrangement system. Internationally, the Swiss wheel is the most widely used in many competitions, and the team of the Swiss wheel must be even.
