Latest on Hackage:0.6.2

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

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 (see Funsat.Resolution) and a logical circuit interface (see Funsat.Circuit). New in 0.6.2: works with ghc-6.12 and fixed some space leaks. =/
