sat-toolkit 0.4.3

Tool for manipulating CNF formulas

SAT-toolkit

A tool for efficiently handling CNF and DNF formulas in Python

Installation

To install from pypi use:

pip install sat-toolkit

To simplify CNFs and convert DNFs to CNFs, you need to compile espresso and make it available on inside your $PATH.

Usage Example

The following example shows how to create a minified CNF for a boolean function that is true at values 0, 6, 9, and 15.

from sat_toolkit.formula import CNF, Truthtable
import numpy as np

table = np.zeros(16, int)
table[[0, 6, 9, 15]] = 1

tt = Truthtable.from_lut(table)
cnf = tt.to_cnf()
print(cnf)
