One of the possibilities to organize a competition is through a drainage system. Characteristic of waste systems is that the participants in the couples against each other and the loser is eliminated. The winners will continue until there is one on the master. Several variants of the waste systems are known and this article describes the simple waste systems.

Waste system only

This is the simplest form of a system for the disposal of waste. In this system, each participant who loses once, turned off for the Championship. It is mainly used for individual events where participation is high and/or the game is long. It also occurs in games where a different system is not possible. At boxing matches bijvoorbeeldkan loser is often not a boxing game.

To put together a system is simple. Take the example of a contest with eight participants. We make four pairs and the winner moves on to the next round. This results in two games by two participants. The final winners will play the final. Graphic suggests that a kind of tree where each branch parts. The participants are divided into tree. This can be done by pulling, but it has the disadvantage that the two best players in theory already in the first round can play against each other. Most organizers do not want this. Therefore, the schema ready so that the numbers 1 and 2 of the list ranking can only get into the final against each other. The number of 3 and 4 of that list only semifinalsna against # 1 and 2, and so on.

A disadvantage of such a system is that you have to start with a number of operators that are a power of two. The number of players is not consistent with a power of 2, then the first round is usually played. In the first round must be played so many matches there after the first round, the number of players back to a power of two. For examples, see 74 participants, you must lose 10 players and therefore must play 10 matches. After the first round, there are 64 players left, only a few who can fill out a schedule.

If it is to play a qualifying round, there are two methods to determine who will play a qualifying round. The easiest method is by means of a lottery. Another method is used when it is not done by placement.

Appearances and number of laps

The number of matches and the number of rounds depends on the number of participants. The number of matches to be played is equal to the number of participants minus 1. Every game there are actually of a participant. To invite a hundred participants to determine a winner as 99 matches. The number of rounds is determined by power of 2 which includes the number of participants.

Is the number of participants between the rules then it will take a first round. The number of rounds is on the next line, and the number of games remaining N-1. Are the participants say 200 players, there are eight rounds and 199 matches.

Advantages and disadvantages

Advantages

- It can be a winner relatively quickly identified, even if the number of participants is high
- The winner is always an undefeated champion
- The schedule calls for the game is not much work. The next game is ready to play

Cons

- After a round is already half of the participants are of
- A challenger can already after an unfortunate defeat are turned off
- The loser of the semi-final is not always the second-strongest player. It may well be that almost half of the participants are better if the losing finalist
- In addition to the numbers 1 and 2, there is no end point. Between numbers 4 and 8 are no difference.

In summary, the simple waste system easy to apply and can be used for example to organise a kind of Cup competition in addition to a regular competition. It is better to divide the best players by position in the various branches of the schedule in the early Shutdown prevents this by favorites.
