Generic SAT solver

About

This repository contains code for a generic SAT solver to solve SAT problems in the DIMACS format.

Requirements

Python 3, numpy

Running Instructions

For Windows:
Run "SAT.bat -Sn input_file.txt" in command prompt.
For Unix based systems:
Run "sh SAT.sh -Sn input_file.txt" in the terminal.

Description

The following heuristics are implemented:
S1: Random Heuristic
S2: Deterministic Two-Sided Jeroslow-Wang Heuristic
S3: Probabilistic Two-Sided Jeroslow-Wang Heuristic
S4: Deterministic DLIS Heuristic
S5: Probabilistic DLIS Heuristic

Additional Notes

For repeating our experiments mentioned in the report (if needed), please follow the following steps:

1. run translate_examples.py under tests/ to encode all test cases in DIMACS format.
2. run samples_tests.py under tests/ to sample test cases from different categories.
3. run run_experiments.py under the main folder to run the experiments.
