Take the above 16 people (teams) as an example. Can be divided into four groups, each group is exactly four people (teams), according to the above group's top 2 (or first) for qualifying, and then cross-race, until the final. In order to make each team's game as fair as possible, it is necessary to adopt a serpentine arrangement, that is, each person (team) has a number from 1 to 16, in which the smaller the number, the higher his ability and level, and 1 6 is the strongest and the weakest.
The four groups are as follows:
Group 1: 1 8 9 16
Group 2: 2 7 10 15
The third group: 3 6 1 1 14.
Group 4: 4 5 12 13.
The sum of each group of figures is the same, indicating that their strength is balanced.
1+8+9+ 16=34
2+7+ 10+ 15=34
3 + 6 + 1 1 + 14=34
4 + 5+ 12+ 13 =34
There are several possibilities for the landlord's problem. If there was a ranking in the last competition, it would be easy. If there are four players in the last game, the number of 1 will be given directly to the last champion. If runner-up No.2, runner-up No.3 (runner-up) and runner-up No.4 (runner-up) are tied for third, third and fourth place, lots will be drawn. If the top eight are allocated in order, and if the top four are tied for fifth place, then four of them will draw No.5, No.6, No.7 and No.8, and the rest will draw No.9-16.
If it is the first time to hold an event without previous achievements, the Organizing Committee of the Games can determine or call the designated seed player 1-4 (or only 1 and 2) according to its own knowledge, and others will draw lots to draw which number is which number.
And there can't be seeded players. Will be positioned by lottery.
In any case, except for the last seed player, the tournament should be artificially separated from the same association (unit) when grouping, and try not to be in the same group.
The above is for the landlord's reference, which can be regarded as mutual exchange and learning ~
