%description
A monad for expressing SAT or QSAT problems using observable sharing.
For example, we can express a full-adder with:
> full_adder :: Bit -> Bit -> Bit -> (Bit, Bit) > full_adder a b cin = (s2, c1
|| c2) > where (s1,c1) = half_adder a b > (s2,c2) = half_adder s1 cin
> half_adder :: Bit -> Bit -> (Bit, Bit) > half_adder a b = (a `xor` b, a && b)
/Longer Examples/
Included are a couple of examples included with the distribution.
Neither are as fast as a dedicated solver for their respective domains, but
they showcase how you can solve real world problems involving 10s or 100s of
thousands of variables and constraints with `ersatz`.
