Description

Is it possible to adapt the open-source implementations to accelerate the Muzero-General?

Here are a few repos that implement Batch MCTS that accelerates the tree search process.
https://github.com/marrekb/MuZero
https://github.com/YeWR/EfficientZero

The repo Omega also implements a novel search policy from Monte-Carlo tree search as regularized policy optimization that can be enabled to improve the efficiency of MCTS, which can be very helpful when the simulation budget is small or the branching factor is huge.

This is a version that incorporates c++ implementation

Thank you!
