The Kissat SAT Solver

Kissat is a "keep it simple and clean bare metal SAT solver" written in C. It is a port of CaDiCaL back to C with improved data structures, better scheduling of inprocessing and optimized algorithms and implementation.

Coincidentally "kissat" also means "cats" in Finnish.

Run ./configure && make test to configure, build and test in build.
