This paper only introduces and explains the provisions on the position of seed players and the position of bye in the lottery of badminton elimination tournament of the International Badminton Federation.
* * * a * * * "seed" position and the provisions of the lottery method.
"Seed" lottery method and lottery location shall meet the following requirements:

2. If there are four "seeds", locate 1 and No.2 "seeds" according to the above method. By drawing lots, No.3 and No.4 "seeds" enter the top of the second 1/4 area and the bottom of the third 1/4 area respectively.
3. If there are 8 "seeds", then the 1 No.2, No.3 and No.4 "seeds" will be carried by the above-mentioned lottery method, and other "seeds" will enter each 1/8 area without "seeds" by lottery: in1/which belongs to the upper half.
Two "seeds" belonging to the same unit should be divided into two and a half regions respectively; If there are three or four "seeds" in the same unit, they should be divided into different areas of 1/4.
Except for "seed", other participants belonging to the same unit should be distributed in different areas 1/2, 1/4, 1/8 in a reasonable and even manner according to the above spirit.

2. When the number of participants * * * or the logarithm * * * is not a power of 2, there should be a bye in the first round, and the bye number is equal to the power of 2 greater than and closest to the number of participants minus the difference of the number of participants.
3. If the bye number is even, the bye positions should be evenly distributed at the top and bottom of the table.
The bye position of the upper part is arranged from top to bottom, and the bye position of the lower part is arranged from bottom to top.
If the bye position is odd, that is, the lower half has one more bye than the upper half.
Example: 1: 10 people take part in the competition, and the bye number is 6 *** 16 10=6***, with 3 bye spaces at the top of the upper half and 3 bye spaces at the bottom of the lower half.

The ranking is determined by the number of * * * wins or * * * wins of athletes.
If two teams and nine teams have an equal number of wins, the ranking will be decided according to the outcome between them.
In case the three teams win more than * * * * or the number of times is equal to * * *, the negative total number of games will be subtracted from the total number of wins or the number of times * * * *, and the net winner will be ranked first; If they are still equal, they will be ranked according to the number of net wins; if they are equal, they will be ranked according to the score of net wins.
If the rankings of the two teams are still uncertain after calculating the net wins of a certain level, it is necessary to further calculate the net wins of the two teams in the next level until the order can be determined. "People also:
