AiAi is a Java-based general game playing engine based on Mogal (a GGP designed and developed by Stephen Tavener and Cameron Browne). Games can be hand-coded in Java (for efficiency), or assembled from blocks using a scripting language based on JSON.
AiAi allows you to play games against a variety of AIs, mostly variations of MCTS (Monte Carlo tree search). It also contains analysis tools for game authoring; though these are more for my benefit than anyone else’s at present!
AiAi is still very much in a state of flux, and rather lacking in documentation at present but I will link documentation here as I write it! Questions and comments welcome, and may well encourage me to write more!
I have added some threads to BGG for announcements, suggestions, and bug reports:
Announcements – subscribe to this thread to be notified when I update Ai Ai
Suggestions – any suggestions for improvements/new features should go here
Bug Reports – find a bug? Report it here. I will probably ask you for a save game file if it is a problem with a specific game.
FAQ – living FAQ; I will update the top post with questions and answers.
The latest version of AiAi will always be available here:
