I have been researching rating systems (first Elo, then Glicko) and found out about your TrueSkill method. I do not know F# but can I use your code to analyze a CSV file with the same format as the one you have? Thanks

Hello again. I compiled the code and tested a subset of the data. My question is it possible to change the parameters to replicate the the TrueSkill calculator does? It seems the code is only to test paired teams. I am looking into ranking players on a 8-player team with no possibility of a draw. I can run the calculator for each game but that is too tedious. I was very excited that there is a system to rank teams now and was hoping there is an automated way to do that (e.g., your console app). Also, before I knew about this system, I was using Elo to rank players on a 8-player team and I had to split it up to heads-up matched (e.g., 1-2, 1-3...., 1-8) to get a ranking. I thought this was OK since 1 beat 2 - 8, etc. But your research paper said that Elo was only for heads-up ranking. How come my method is no good? Thanks again.

There is a problem with your F# code for the latest F# release. VS 2010.

Your problem lies in the Microsoft.FSharp.Reflection.Value namespace, which is not available on the newer releases of FSharp. I researched all FSharp libraries to find out where the types like GetSumTagConverters, GetSumTagReader and IsOptionType has gone to, but all of them seem to have disappeared from the radar.

This code breaks with recent releases (May 2009 CTP and VS 2010) of F#. The reason for the break is the absence of the namespace Microsoft.FSharp.Reflection.Value, which contained functions like IsOptionType, GetSumTagReader and GetSumTagConverters. These functions have since disappeared from the radar and the original page on Microsoft.com explaining this has also disappeared (supposed to be: http://research.microsoft.com/fsharp/manual/FSharp.Core/Microsoft.FSharp.Reflection.Value.html), leaving me at a loss to how to change your code, now knowing what the original functions were supposed to do.

Is it possible for you to update the code to compile on the recent CTP releases of F# or to give a hint how to resolve these errors?

Thanks,

@Daren: looks like my text on Experts-Exchange ;-). Sorry, didn't see your post before I posted mine.
