I checked https://github.com/YeWR/EfficientZero 's implementation of MCTS(based on c language), and am almost certain we should reverse search_path.

Hi @ChenDRAG,
Thanks for finding this potential bug. Superficially, it does look that it should be reversed.
I would get back to this in a day or two to investigate its correctness.
Also, I am also happy to accept a PR on it.

The authors corrected the mistake of not reverseing the search_path in the v2 of the pseudocode. Another small error is that the target rewards seem to be misaligned, there is a thread on stackoverflow about that: https://stackoverflow.com/questions/60234530/is-the-reward-value-in-muzeros-pseudocode-misaligned
