How do I download the simulation to train the AI bot

It’s my first time participating at this contest. I’d like to be able to download the simulation on my machine, so that I can easily train my AI bot which uses a Genetic Algorithm.
I saw the link to the github, but it doesn’t work.
Any suggestions?

The brutaltester will help you to run battles offline.
Either modify the referee yourself to be compatible with that or wait until someone else does that for you.

It’s look like KevinBusse coded a referee for MeanMax :
Never tried it so i can’t say if it works properly.
