Calculation of the number of single cycle games.
The formula for calculating the number of players in a single round-robin game is: X=N(N- 1)÷2, that is, the number of players in the team × (the number of players in the team-1)÷2.
For example, 8 teams participated in the competition, with a total of 28 games.
The purpose of calculating the number of games is to calculate the number of venues needed for the game, and then consider the number of referees and how to arrange the game schedule.
3. Arrangement of single round robin competition
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 can keep the final game exciting, which is the usual arrangement method.
In the case of five teams participating in the competition, you can add "0" to arrange them.
The following methods can usually keep the final game exciting, which is a common arrangement method.
In order to avoid uneven work and rest, you can also put "0" in the lowest position on the far right and keep it still.
After the round-table meeting is arranged, each team draws lots, fills in the round-table meeting according to the number drawn by each team (or determines the number according to the ranking order of the last game), and then prepares the competition schedule. When compiling the competition schedule, we should first implement the principle of equal opportunity and fair competition, and of course, we should also take care of the needs of the competition (audience) appropriately. We can adjust the time (morning, afternoon, evening), venue (large or small pavilion), region (local or foreign) and other aspects to achieve a general balance between teams.
In the arrangement, the interval between rounds should be considered to ensure that athletes have enough rest time. If the competition cycle allows, you usually have to take a day off after three rounds. The color of the clothes should be implemented according to the rules, that is, the top team (home team) of the squadron in the order book should wear dark clothes. Pay attention to leaving time for washing and drying when finishing.
