pyglucose

pybind11-based binding of glucose SAT solver.

Installation

pip install git+https://github.com/msakai/glucose-pybind11/

Basic Usage

The pyglucose module exports Solver and Lit.

A SAT problem can be solved as follows:

1. Construct a solver instance using solver = Solver().
2. Allocate variables using var = solver.new_var(). A variable is returned as integer value and can be converted to Lit by Lit(var). A literal lit can be negated as ~lit.
3. Add clauses using solver.add_clause(clause). A clause is represented as Iterable[Lit].
4. Solve the problem using solver.solve()
5. If solver.okay property is True then the problem is SATISFIABLE, and satisfying assignment can be retrieved using solver.model property. Otherwise, the problem is UNSATISFIABLE.
