Environments
We support environments ranging from MORL literature to inherently multi-objective problems in the RL literature such as Mujoco. An exhaustive list of environments is available on our [documentation website](https://mo-gymnasium.farama.org/environments/all-environments/).
Wrappers
Additionally, we provide a set of wrappers tailor made for MORL, such as `MONormalizeReward` which normalizes an element of the reward vector, or `LinearWrapper` which transforms the MOMDP into an MDP. See also our [documentation](https://mo-gymnasium.farama.org/wrappers/wrappers/).
