(A) the arrangement of the elimination system
First of all, according to the number of teams who signed up for the competition, each team draws lots to determine their position in the competition table, and then fills in the team name in the competition table. If the number of teams is exactly a power of 2 (4, 8, 16, etc. ), all teams must participate in the first round of competition. If the number of teams is not a power of 2, then after the first round of elimination, the number of teams in the second round must be a power of 2.
(2) Circular arrangement method
1, the calculation of the number of games in a single cycle.
The formula for calculating the number of matches is: number of teams (number of teams-1)/2= total number of matches.
Calculation of competition rounds: If the number of teams is even, the number of competition rounds is-1.
If the number of teams is odd, the number of rounds is equal to the number of teams.
2. Arrangement of the Round Table of the Competition
No matter whether the number of teams is even or odd, they will be arranged in even order. If it is odd, you can add a "0" symbol to make it even, and the team that meets 0 will have a bye.
3. Arrangement of Round Table of Double Round-robin Competition
The round arrangement of the double round robin is the same as that of the above single round robin, but the arrangement of the first round robin and the second round robin is different.
4. Arrangement of grouping cycle
Group round robin is to divide the participating teams into several groups, and each group will have a single round robin first. After the group round robin, the ranking of each group will be ranked, and then the second stage of the competition will be held.
(3) Arrangement method of hybrid system
The competition of adopting the above two systems at the same time is the mixed system. The mixed system is divided into two stages, the former adopts the group elimination system and the latter adopts the circulation system, the former adopts the group circulation system and the latter adopts the elimination system.
Fourth, the calculation method of basketball match results
(A) the method of calculating the results of the elimination system
The elimination system can only reasonably determine the first place, and when it is necessary to determine the ranking of other teams, a "play-off" will be held. The way of make-up should be clearly stipulated in the rules of the game. The usual make-up method is: the team that failed in the final is the second; The two teams that lost in the semi-final make-up once, the winner is the third and the loser is the fourth. The four teams that failed before the rematch played a rematch for the fifth to eighth place.
(B) the calculation method of the results of the round robin system
In the round robin system, when determining the ranking of the competition, it is calculated according to the points, that is, winning a game will get two points, losing a game will get one point, and abstaining will get zero points. Those with more scores rank first.
If the scores of several teams are equal at the end of the game, the rankings are arranged as follows:
1. If the points of two or more teams are equal, the winning team in the two teams will be ranked first.
2. If the scores of the two teams are equal, the ranking will be based on the number of winners and losers between the two teams with equal scores; If they are still equal, they are ranked according to the gain and loss rate of the game between them (that is, the total score/total loss). If they are still equal, they will be ranked according to the gain and loss rate of all the games in the whole group.
(3) Calculation method of hybrid system performance
If * * * is divided into two groups, the first stage adopts grouping cycle. In the second stage, according to the corresponding rankings of two groups (namely, the first and second places of two groups), the competition will be conducted in a cross way. The two winning teams will compete again to decide the first and second place, and the two losing teams will compete again to decide the third and fourth place. The third and fourth places generated by the original grouping cycle are also determined in the same way.
