toysolver

Hackage:

Dev:

It provides solver implementations of various problems including SAT, SMT, Max-SAT, PBS (Pseudo Boolean Satisfaction), PBO (Pseudo Boolean Optimization), MILP (Mixed Integer Linear Programming) and non-linear real arithmetic.

In particular it contains moderately-fast pure-Haskell SAT solver 'toysat'.
