- Funsat: A DPLL-style SAT solver in pure Haskell
Funsat is a native Haskell SAT solver that uses modern techniques for solving SAT instances. Current features include two-watched literals, conflict-directed learning, non-chronological backtracking, a VSIDS-like dynamic variable ordering, and restarts. Our goal is to facilitate convenient embedding of a reasonably fast SAT solver as a constraint solving backend in other applications.
Currently along this theme we provide /unsatisfiable core/ generation, giving (hopefully) small unsatisfiable sub-problems of unsatisfiable input problems (see "Funsat.Resolution").

Installation Install using the typical Cabal procedure:
$ ghc --make -o Setup Setup.hs $ ./Setup configure $ ./Setup build
This will produce a binary called funsat at ./dist/build/funsat/funsat and a standalone library interface for the solver. If you feel like profiling the code, a profiling binary is automatically built in ./dist/build/funsat-prof/funsat-prof.
