@hackage funsat0.5.1

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).
