If you want to reproduce our paper experiments:

• the notebooks here and here reproduce the experiments
• thise code contains implementation the protocols used for the numerical experiments of our article.

In order to use our MGS strategy:

• this notebook illustrates how to use it
• the strategy is implemented here
