Testing at home
Caia is a system that you can use to test and improve your CodeCup submission from home. Caia is used by both advanced competitors as well as beginners.

Caia
The Caia Project is the result of the need to have software to play competitions between programmed client players of strategic games from their own homes. That software is now available under a Linux environment.
Jaap Taal and Marcel Vlastuin developed a home edition of the jury software and published it as open source. The project Caia consists of several components:
- The program caiaio, which is written in the language C++. This is the main program that takes care of the input and output and is ready-to-use. Caiaio stands for: Caia-input-output.
- Programs that have to be written by the user are: a manager, a referee and, of course, the players themselves. The referee and the players are game dependent; the manager is not. The programs can be written in any language, you'll just need to provide an executable program. C, C++, Pascal and Haskell programs are typically compiled, Python scripts can use a shebang line. Java programs will need a shell script so that caiaio can start it without parameters. On windows you'll need a small executable for Java and Python scripts, batch files won't work.
- The protocol that explains how the referee, the manager and the players can communicate with the caiaio and the others.
- Ready to use system for this year's competition, including a referee and some test players from the CodeCup site.

For a reference about how to install and start Caia please download the tutorial below on this page for your operating system.
Competition Manager
The competion manager can organise full competitions.
This new manager can replace the normal manager executable if you don't just want
to test your program, but with the competition manager you can organise a competition where
each of your programs play against all other programs.
The competition manager is included in all distributions of Caia.

There are five different versions of the Caia-distribution for the game Flippo:
To get started, please take a look at the Caia tutorial.
Our experience with Caia learns that it runs best under Linux.
For Windows users, we recommend using the Windows subsystem for Linux in which the Linux version of Caia can run. One could also try cygwin under windows. Read more about Cygwin on www.cygwin.com.
Old Caia distributions
The first caia distribution was published in 2004 (CodeCup 2005). This old package (which uses an outdated caiaio) contains examples for the referee and the manager. You can use these examples. It is adviced to replace the caiaio files, which are included in the Caia-distribution for the game of this year.
