On a my-friends-stood-me-up-to-go-out Saturday rage i wrote the code to run and compare different rating systems.
You can see some guidelines and the code here : https://github.com/conanbatt/OpenKaya/
Anyone that desires to try out and implement a rating system and compare it to others can do so. I am contacting some mathematicians and programmers that enjoy the rating systems problem, and if anyone here wants to get involved he can. Im available for questions and even aid.
If you know someone that would be interested in doing such a thing, tell them! the more rating systems we have, the better.
By the time we lanuch i will implement a simple Elo based system which will be sufficient considering we wont have many players, but afterwards i want to make the best community-oriented decision on which rating system will be used in Kaya.
Tell your geek friends!
