What Is a Shakeout?

Elimination matches refer to a system of sports competitions and various other competitions in which players compete against each other and lose out. Eliminate half of the players in each round until the final champion. In the single elimination system, the organizing committee will arrange all players in advance according to the ranking or seed order, and also supports the arrangement of some seed players to start the game directly from the middle round (that is, by-pass). The purpose of this is to prevent the strong players from meeting prematurely, resulting in too much disparity between the strengths of the two sides in the subsequent games, affecting the suspense and excitement of the game.

The round-robin system is a method in which each team can play once or twice with other teams, and finally calculate the ranking according to the results. This method is more reasonable, objective, and fair, and is conducive to the learning and exchange of experiences between teams. ^[1]

Single cycle is that all participating teams can meet once. Finally, according to the points of each team in all matches,

The single-loop competition sequence is usually arranged in a rotation method.

Regardless of whether the number of participating teams is even or odd, they should be arranged in even numbers. If it is an odd number, you can make up a "0" number, and the team that meets "0" will take a turn once.

For example, when there are 8 teams participating, their arrangement is shown in Table 1-1. Graph display

This rotation method is suitable for teams that don't understand each other's strengths. Therefore, it is very likely that strong teams will meet early in the lottery.

"Counter-clockwise rotation", this arrangement method can keep the final game exciting, and it is the usual arrangement method (Table 1-2). Graph display

In the case of 5 teams participating, they can be arranged by adding "0", as shown in Table 1-3. Graph display

The following methods are usually used to keep the final match exciting. They are the commonly used methods, as shown in Table 1-4. Graph display

In order to avoid uneven work and rest, you can also put the "0" to the bottom right position and keep it still.

After the round table is arranged, each team draws lots and fills in the round table according to the number drawn by each team (or determines the number according to the order of the previous competition), and then compiles the competition schedule accordingly. To organize the competition schedule, we must first implement the principles of equal opportunities and fair competition. Of course, we must also properly cater for the needs of the competition (spectators). Regional (local or field) adjustments are made to achieve a general balance between the teams.

In the arrangement, the length of the interval between the rounds must be considered to ensure that the athletes have sufficient rest time. If the competition period allows, it usually takes a day off after three rounds. The color of the clothing should be implemented according to the rules, that is,

Double-loop, where all participating teams can meet twice. Finally, according to the points of each team in all the games in the two loops,

The group cycle is to divide all participating teams into several groups for the first stage preliminaries, and then the second stage finals between the winning teams in each group to determine the first and lower places. The single-loop competition method is used in the group preliminary competition, and it can be used in the finals.

For example: there are 16 participating in the game. In order to make the number of teams in each group equal, they can be divided into 4 groups with 4 teams in each group. If time and funding allow, and you want to play more games, you can also divide into two groups of 8 teams each. In the division into 4 groups, the "seed team" can set up 4 teams or 8 teams, which can be drawn into the group by lottery, or 1, 8, 2, 7, 3, 6, 4, 5 (according to The ranking of the previous competition was eliminated) and drawn into the group by lot.

For the rest of the serpentine arrangement method, the "seed teams" of 1, 4, 5, and 8 are placed in the first group, and the "seed teams" of 2, 3, 6, and 7 are placed in the second group. Inside.
