GAMSPy Modeling Examples

This repository contains many examples to show how to model mathematical optimization problems by using GAMSPy. The example models are distributed as either Python script files (under models) or Jupyter Notebooks (under notebooks).

Installing Dependencies

git clone [email protected]:GAMS-dev/gamspy-examples.git
pip install -r requirements.txt

Running Locally

cd <model_directory>
python <model_name>.py

Licensing

GAMSPy pip package includes a demo license. For most of the notebooks, this demo license is sufficient. For others, you may need a different license (See Licensing). In case you already have a GAMSPy license, see GAMSPy License Installation guideline.
