What is the progressive division of Swiss Go rules?

Swiss competition system is one of the special competition systems of chess competition, also known as integral round robin. The principle is to avoid the seed players fighting from the beginning. It is a scientific, reasonable and widely used competition system so far. Integral round robin, the first round of competition is arranged randomly and fairly, and then the competition begins. When a certain round of competition is over, you can get the current total scores of all the contestants. According to the current total score, the contestants are ranked from high to low, and the high score is higher than the high score, and the low score is lower than the low score. The next round after the last round will not meet, and so on until all rounds are over.

In the round robin, the winner gets 1 point, the winner gets 0.5 point, and the loser gets no point. Swiss-made points are each round of points plus the previous round of points. Specifically, after 1 round: current total score = 1 round; After the second round: current total score = 1 round score +2 rounds score, and so on.

If the competition ends and the same score appears when judging the ranking, you can rank according to the following rules to break the same score:

1. Bushholtz system (small score system): Bushholtz system, also known as small score, refers to the score of every opponent he meets. If the points are the same, first add up the points of each opponent to get a small sum, and then rank.

2. Progressive scoring system: If the integral and the fraction are the same, you can get the total progressive score by accumulating the points of each round of players, and then rank them.

3. Straight win system: When all players with the same score, small score and progressive score are the same, if the players have met, the outcome will be judged according to their meeting.

4. Number of chess wins: When all players with the same score, small score and progressive score are the same, if the players have never met, they will be judged according to the number of chess wins.
