as4moco

Algorithm selection for model counting

as4moco uses algorithm selection and automated algorithm configuration decrease its solving time for #SAT queries. It is based on AutoFolio, an algorithm selection framework.

Requirements

  • Java 21
  • Python 3 (tested for Python 3.10)
  • Ubuntu 22.04 (other version may require a recompilation of the used solver binaries)

How to install

  1. Install modified AutoFolio
    1. Create a new virtual environment: python3 -m venv <Name of Virtual Environment>
    2. Clone modified AutoFolio: git clone https://github.com/RSD6170/AutoFolio/
    3. Install the modified AutoFolio package: <path to venv>/bin/python3 -m pip install <path to cloned repository>
  2. Clone this repository: git clone https://github.com/SoftVarE-Group/as4moco
  3. Modify AlgorithmSelector.java at marked todo with path to python venv and AutoFolio repository: private final static String[] commands = new String[]{"<Path to Python Venv>/bin/python3", "-u", "<Path to AutoFolio repo>/scripts/java_bridge.py"};

How to run

Run Gradle::run with your parameters

Example for Ubuntu: ./gradlew run −−args="−modelFile </path/to/af_model.pkl> −cnfFile </path/to/cnf.dimacs>"

New model files can be created, refer to the example in the AutoFolio repository.
