OMMX

Open Mathematical prograMming eXchange (OMMX) is an open ecosystem that empowers mathematical programming and optimization developers and reserchers.

Design

OMMX introduces two specification to solve the problem of data exchange in optimization field:

• Protocol buffers based data schema called OMMX Message. This helps to store the optimization models and their solutions in language and framework agnostic way.
• OCI Artifact based packaging and distribution specification called OMMX Artifact. This helps to store your data with metadata and to exchange them with others as a container image.

To run the notebooks locally, you need to install required packages listed in requirements.txt

# Optional: create a virtual environment
python -m venv .venv && source .venv/bin/activate

# Install required packages (including Jupyter)
pip install -r requirements.txt

# Start Jupyter
