Why do tennis players have to say what seed number?

In order to keep the competition exciting, seed players (ranked by points) are set up to ensure that the competition will become more and more exciting. However, if high-level players meet too early, some people will be eliminated, and the organizing committee often relies on those high-level players to attract popularity.

According to the lottery rules for singles events:

1. Arrange the seeds of 1 and 2 first, and divide the signing table into two areas, with 1 and 2 each occupying an area, so as to ensure that the first two seeds will not meet before the final.

2. Rearrange the No.3 and No.4 seeds, and divide the two areas divided by 1 and No.2 seeds into four areas. Draw lots to decide which remaining 1/4 area the third and fourth seeds are in. Make sure the top four seeds don't meet before the semi-final.

3. Then arrange the seeds No.5, No.6, No.7 and No.8, divide each 1/4 area evenly, and draw lots to decide which of the remaining 1/8 areas these four seeds are in. Make sure that the first eight seeds will not meet before 1/4.

4. And so on in the future. The number of seeds is set to 65438+ 0/4 of the number of participants to ensure that all seeds will not meet in the first two rounds. Therefore, there are 32 seeds in the Grand Slam with a seat of 128, which ensures that these 32 seeds will not meet before the third round.

In this arrangement, the top two seeds can only meet in the final; If the top four seeds can meet, they can only meet in the semi-finals ..... but save the best for last. On the other hand, players also try their best to improve their rankings to prevent themselves from meeting other seeds or top-ranked seeds prematurely and being eliminated prematurely.
