GDC 2011 - a quick overview!

Ralf Herbrich is the man behind the TrueSkill ranking system used in Halo and elsewhere. He is also the director of Fuse Labs in the UK and stops by our studio to talk about how TrueSkill was invented and where it's going in the future.
There is a lot of additional information available on True Skill that it would be handy to link to:

Even a F# True Skill implementation https://blogs.technet.com/b/apg/archive/2008/06/16/trueskill-in-f.aspx
and a C# one with a great detailed article about it http://www.moserware.com/2010/03/computing-your-skill.html
Oh i missed that when i skimmed the blog post, i had it on my "to read list"
Thanks for pointing it out :)
Although i'm disappointed that there isn't a C++ version...
I am wondering that I can find this post I really need this information and at last today I find it, thank for sharing such a nice information with me and with other user thanks a lot and great wishes, thanks
Whoah, Head To Head, i really wish i could have experienced that, but it was before my time, as i started playing Halo 3 in the summer of 2008, right before the new ranking system was implemented; what a blast from the past.
