Required prerequisites

• I have read the documentation https://omnisafe.readthedocs.io.
• I have searched the Issue Tracker and Discussions that this hasn't already been reported. (+1 or comment there if it has.)
• Consider asking first in a Discussion.

Questions

The code of omnisafe/algorithms/model_based/planner/cce.py andomnisafe/algorithms/model_based/planner/rce.py is exactly the same.

Hi, Jackory!
You can see the distinctions between them in the following link. RCE uses the maximum cost from the ensemble model to evaluate the entire set of trajectories, while CCE utilizes the mean value

Oh, I see. Thank you for your thoughtful reply!
