satisfy them booleans, solve them integers.
cnf.py is a small library for creating formulas in conjunctive normal form,
and also for dealing with the eponymous CNF file format.
the types used internally and exposed externally are very simple:
booleans, integers, and lists of each.
z0.py is a slightly larger library that builds upon cnf.py,
mimicing a tiny subset of the z3
library's interface. it exposes classes for high-level bitvectors and
unary-encoded integers.
(unary is sometimes more efficient to solve)
sugarcane4unary2.py utilizes z0 to solve a (pretty arbitrary) problem
relating to farming sugarcane in Minecraft. you will need to set
the environment variable SOLVER to (the path of) an external SAT solver.
kissat works well.
hex_problem.py creates a hexagon grid with some colored numbers in it.
it doesn't really a serve a purpose.
yices_solution.py parses a solution from a SAT solver,
given the original yices-generated CNF.
