Code release?

I've read your paper on deep neuroevolution and found it very interesting.

A few basic questions:

  • When can we expect a code release?
  • Do you use a GPU to evaluate neural networks, or is everything CPU-based?
  • Could you share more details about the machine you trained on? You say it is a 32-core CPU machine, but is that 32 cores, or 32 threads?
  • Did you use any tricks to speed up the evaluation of neural networks / policies?
  • Is this implemented in Python + numpy?

Hi, glad you found the paper interesting! The code is now online. It's implemented in Pytorch and we used a machine with 32 virtual CPU cores.

We used one trick to speed up evolution, which we also detail in the paper: evaluations are terminated early if the car drives outside of the track for a certain number of timesteps.
