Single round robin is that all participating teams can meet once, and finally rank according to the points and gains and losses of each team in all competitions. If there are not many teams and the time and space are guaranteed, this kind of competition is usually adopted.
Generally, the arrangement of single-cycle competition sequence adopts rotation method.
No matter whether the teams are even or odd, they should be ranked even. If it is an odd number, you can add a "0", and the team that meets a "0" will have a bye.
For example, when there are eight teams competing.
This rotation method is suitable for teams that don't know each other's strength, so it is very likely that the strong teams will meet in advance by drawing lots and positioning.
"Counter-clockwise rotation" is a common arrangement method, which can keep the final game exciting.
Calculation of the number of single-cycle games;
The calculation formula is: X=N(N- 1)/2, that is, the number of people in line * (the number of people in line-1)/2. For example, 8 teams participate in the competition, and the total number of games is: [8x(8- 1)]/2=28 games.
Generally, the arrangement of single-cycle competition sequence adopts rotation method. No matter whether the teams are even or odd, they should be ranked even. If it is an odd number, you can add a "0", and the team that meets a "0" will have a bye.
