README
Glicko
Haskell implementation of the Glicko-2 rating algorithm by Professor Mark E. Glickman.
Building
Easiest is using stack.
$ git clone https://github.com/Prillan/haskell-glicko.git
$ cd haskell-glicko
$ stack setup
$ stack build
Examples
The test case from the Glicko-2 paper is included in test/Paper.hs.
$ stack ghci
*Main> :l test/Paper.hs
*Paper> :m + Data.Default
*Paper Data.Default> mapM_ print $ compute players matches def
