EfficientZero v2

[esparano]

Hi, are there any plans of implementing EfficientZero v2? I noticed that there is a pull request from half a year ago, and I see something about Sampled EfficientZero, but I'm not really sure whether that is equivalent to V2.

Hi, thanks for your interest!

Indeed, our previous PR #461 was an attempt to integrate EZ-V2. However, due to other ongoing internal priorities, this work has not been fully advanced and likely won't be a focus in the near term. That said, we do plan to integrate it in the longer term. If you have the time and interest, we'd be very happy to discuss and collaborate on moving this forward 👏

One clarification: Sampled EfficientZero is an extension of EfficientZero that incorporates the continuous action handling from Sampled MuZero — it is not a reproduction of EZ-V2, although the underlying principles are similar.

Thanks for your suggestion!
