Three people play a single round robin, * * * counts three rounds of B-C A-C A-B CA-B, and there can only be two situations (each person plays twice). The first is that someone wins 2 games; Some people win and some people lose, and some people lose in both wars. The second situation. : all three have won and lost.
In the first case, the ranking is very good. The winner, champion 1, winner 1, is the runner-up, with two games lost, ranking third.
The second situation is the chain, where A wins B and C wins A, and the first thing to see is who wins more online and who wins first; At this time, if one person wins the online match more than two people, this person is the champion. If the other two win the online match, it depends on the relationship between the two in the round robin, and the winner ranks first. If the three people are still the same net win at this time, look at their total score of goal difference (small score)-total lost score = net win score, and many of them are ranked first. At this time, the scores of the two net wins are the same. Similarly, the winner ranks first in the round robin.
If it is rare for three people to win, win and win, we can only use the most cruel means of "drawing lots" to determine the ranking. There is no other way, and overtime and rematch are not allowed. The method order of badminton ranking is victory times (number of victories), net victory, net victory and lottery (in case of indistinguishability). Actual operation: list the winning times first, and the following ranking items will not be compared, both of which are the same, depending on the winning-losing relationship; If more than three people are the same, most of the top ranking items are listed first, and the remaining two items are the same, so there is no need to continue to compare the ranking order (for example, if three people have the same wins, one person wins the net game first, and the remaining two people have the same net game, then directly look at the winning relationship, not the net winning points of these two people).
