Meta-Reinforcement Learning (MRL) is a promising framework for training agents that can
quickly adapt to new environments and tasks. In this work, we study the MRL problem under
the policy gradient formulation, where we propose a novel algorithm that uses Moreau
envelope surrogate regularizers to jointly learn a meta-policy that is adjustable to the
environment of each individual task. Our algorithm, called Moreau Envelope Meta-
