Comment (by msoos):
I'm the author of CryptoMiniSat. The 3.x series doesn't support XOR
naively. It should be much faster on many instances, though, and has
substantially improved in stability and with 3.4 a much cleaner interface
too. I am planning on a python interface, too for 3.4 which should make
things drag-and-drop from your perspective. See
https://github.com/netom/satispy for an example.
As a library, 3.x it doesn't need boost, zlib, mysql or m4ri, but needs
C++11. It's 2014, so it's been 3 years now, I hope that's okay :S C++11
substantially increases portability due to uint32_t/uint64_t and threads
being part of C++11, not to mention the readability of the code. As for
cmake, I think I'll make a simple automake version as well. I'll update
this ticket when 3.4 is released.
BTW, 3.x supports DRUP (http://www.cs.utexas.edu/~marijn/drup/), which
means UNSAT can be verified(!) and potentially traced back to the exact
clauses causing UNSAT. This means that the solver can give more meaningful
feedback than just a 1-bit value (UNSAT) in case it's not SAT -- in which
case it gives a satisfying assignment, a very helpful trace.
