The competition of sixteen teams can be divided into groups and then divided into three stages. The first stage of grouping can be divided into four groups: A, B, C and D, with four teams in each group. The serial numbers of the grouping teams are determined by drawing lots (for example, A 1. A2.A3.A4)。 Then adopt the group round robin system (such as A1-A2A3-A4; A 1-A4，A2-A3； A2-A4, A 1-A3) As long as there is enough space, it won't take long for four groups to play at the same time. If it is a school game, eight games a day will be played at the same time. It only takes three days, and the first stage of the game is over. The top two in each group are eligible to enter the second stage. Then in the second stage, the single round robin system is generally simple. For example, the first place in Group A is against the second place in Group B, the first place in Group B is against the second place in Group C, the first place in Group C is against the second place in Group D, and the first place in Group D is against the second place in Group A (this is just an arrangement, and similar arrangements can be made according to the situation). The winning team qualified, leaving only four teams for the third stage. Divide into group A and group B, and draw lots to decide that the two teams of group A and group B will participate in the competition respectively, and the winning team of group A and group B will play again, and one or two people will be separated; The losing team in Group A and the losing team in Group B will play again, and three or four people will divide it. In this way, the competition of sixteen teams is all over.
However, there is also a drawback, that is, the weaker team can only participate in three games, which is not necessarily good! If you want to consider involving more people to achieve your goal, you can use another method, but it is more complicated, and I will write it down below. Generally speaking, the fewer incidents, the better. The fewer events, the fewer problems the stadium may have, and the easier it is for the organizers to manage! Now I'll write you another method ~
It's the same grouping, but there are only three groups, five groups and six groups in group C. The method is the same as above, two teams in group A and B, and three teams in group C. We will enter the next round. At this time, there are seven teams, and the method adopted is to divide them into four groups and draw lots. There is only one team in a group, and it is directly eliminated by bye. The other three teams compete and get the qualification of three teams. Plus the goodbye team, there are four teams in the next round. There is no need to draw lots. The qualifying teams of Group A and Group B compete with each other, and the qualifying teams of Group C and Group D compete with each other. After that, the two teams that won decided one or two, and the two teams that lost decided three or four. The advantage of this is that each team has at least one or two more games than the previous arrangement, and you can arrange them according to your needs ~
I don't know if you know, but if you have any questions, please ask me again. I am a referee, and I have been in charge of many such competitions ~ I hope I can help you!
To supplement the ranking method adopted in the next grouping cycle, the point system is adopted, with 2 points for winning a game, 0 points for losing a game 1 point, and 0 points for abstaining. If the points of the two teams are the same, the winning team between the two teams ranks first. If two or more teams have equal scores, they will be ranked according to the 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 the whole group, and the one with higher proportion will be ranked first. There are four teams in each group, so it is very difficult to meet complicated rankings. As I said, there are six teams in the second scheme that are likely to meet. I don't know if you know the ranking method ~ hehe, do you feel it? It's quite clear ~
