Olympus provides a consistent and easy-to-use framework for benchmarking optimization algorithms. With olympus you can:

• Build optimization domains using continuous, discrete and categorical parameter types.
• Access a suite of 23 experiment planning algortihms via a simple and consistent interface
• Access 33 experimentally-derived benchmarks and 33 analytical test functions for optimization benchmarks
• Easily integrate custom optimization algorithms
• Easily integrate custom datasets, which can be used to train models for custom benchmarks
• Enjoy extensive plotting and analysis options for visualizing your benchmark experiments

You can find more details in the documentation.

Olympus can be installed with pip:

pip install olymp

The package can also be installed via conda:

conda install -c conda-forge olymp

Finally, the package can be built from source:

git clone https://github.com/aspuru-guzik-group/olympus.git
cd olympus
python setup.py develop

You can explore Olympus using the following Colab notebook:

The installation only requires:

• python >= 3.6
• numpy
• pandas

Additional libraries are required to use specific modules and objects. Olympus will alert you about these requirements as you try access the related functionality.

The following projects have used Olympus to streamline the benchmarking of optimization algorithms.

• Bayesian optimization with known experimental and design constraints for chemistry applications
• Golem: an algorithm for robust experiment and process optimization
• Equipping data-driven experiment planning for Self-driving Laboratories with semantic memory: case studies of transfer learning in chemical reaction optimization
