* 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:

    $ cabal configure
    $ cabal 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.

** Testing

All the problems in tests/problems should run through.

  uf20 and uf50 - satisfiable
  uuf50 - unsatisfiable

** Dependencies
All the dependences are cabal-ised and available from hackage, or in etc/.
