glpk-hs

Friendly interface to GLPK's linear programming and mixed integer programming features. Intended for easy extensibility, with a general, pure-Haskell representation of linear programs. Also includes usefully general algebraic structures. To design a linear programming problem, use Control.Monad.LPMonad to construct the constraints and specifications. Linear functions are essentially specified as Data.Maps from variables to their coefficients, and functions for manipulating them are available in Data.LinearProgram.LinExpr. Then Data.LinearProgram.GLPK provides facilities for using the GLPK solver system on your problem, with a sizable number of options available.
