Sparkle is a Programming by Optimisation (PbO)-based problem-solving platform designed to enable the widespread and effective use of PbO techniques for improving the state-of-the-art in solving a broad range of prominent AI problems, including SAT and AI Planning.

Specifically, Sparkle facilitates the use of:

• Automated algorithm configuration
• Automated algorithm selection

Furthermore, Sparkle handles various tasks for the user such as:

• Algorithm meta information collection and statistics calculation
• Instance/Data Set management and feature extraction
• Compute cluster job submission and monitoring
• Log file collection

Installation

The quick and full installation of Sparkle can be done using Conda (For Conda installation see here).

Simply download the environment.yml file from the Github and run:

    $ conda env create -f environment.yml

And afterwards activated by:

    $ conda activate sparkle

Note that the creation of the Conda environment also takes care of the installation of the Sparkle package itself.

The Sparkle package can be installed using Pip. We recommend creating a new virtual environment (For example, venv) before to ensure no clashes between dependencies occur.

    $ pip install SparkleAI

Note that a direct installation through Pip does not handle certain dependencies of the Sparkle CLI, such as the required libraries for compiling RunSolver.

Install dependencies

Asside from several package dependencies, Sparkle's package / CLI relies on a few user supplied executables:

• LaTex compiler (pdflatex) for report generation
• Java, tested with version 1.8.0_402, in order to use SMAC2

Other dependencies are handled by the Conda environment, but if that is not an option for you please ensure you have the following:

• libnuma and numactl for Runsolver compilation which sparkle uses to measure solvers meta data. This is restricted to Linux based systems.
• Swig 4.0.2 for SMAC3, which is in turn used by AutoFolio.

For detailed installation instructions see the documentation: https://sparkle-ai.readthedocs.io/

Examples

See the Examples directory for some examples on how to use Sparkle. All Sparkle CLI commands need to be executed from the root of the initialised Sparkle directory.

Licensing

Sparkle is distributed under the MIT licence

Component licences

Sparkle is distributed with a number of external components, solvers, and instance sets. Descriptions and licensing information for each these are included in the sparkle/Components and Examples/Resources/ directories.

The SATzilla 2012 feature extractor is used from http://www.cs.ubc.ca/labs/beta/Projects/SATzilla/ with some modifications. The main modification of this component is to disable calling the SAT instance preprocessor called SatELite. It is located in: Examples/Resources/Extractors/SAT-features-competition2012_revised_without_SatELite_sparkle/
