Competition types

The ringmaster supports a number of different competition types. These are divided into tournaments and tuning events.

Tournaments

A tournament is a form of competition in which the ringmaster plays games between predefined players, in order to compare their strengths.

There are currently two types of tournament:

• Playoff
• All-play-all

Tuning events

A tuning event is a form of competition in which the ringmaster runs an algorithm which adjusts engine parameters to try to find the values which give strongest play.

At present, all tuning events work by playing games between different candidate players and a single fixed opponent player. The candidate always takes the same colour. The komi and any handicap can be specified as usual.

There are currently two tuning algorithms:

• Monte Carlo
• Cross-entropy
