N-STARK (Non-STAtionary loads Routing on networKs) is a Python implementation of the algorithms used in:

• [1] Alessandro Lonardi, Enrico Facca, Mario Putti and Caterina De Bacco. Infrastructure adaptation and emergence of loops in network routing with time-dependent loads. Phys. Rev. E 107, 024302 [arXiv].

This is a scheme capable of solving network routing problems with input loads injected in the nodes that change in time. Optimal solutions are computed solving a dynamical system of equations.

If you use this code please cite [1].

What's included

• code: contains the all the scripts necessary to run N-STARK, and a Jupyter notebook (dashboard.ipynb) with which it is possible to easily interact with them and visualize the results
• data/input: contains the data needed to build the Bordeaux bus network, where the algorithm can be tested. The network topology has been pre-processed and extracted using [2]
• misc: files used for the README.md
• setup.py: setup file to build the Python environment
