Actor-critic with experience replay (ACER) [1]. Uses batch off-policy updates to improve stability. Trust region updates can be enabled with --trust-region. Currently uses full trust region instead of "efficient" trust region (see issue #1).
Run with python main.py <options>. To run asynchronous advantage actor-critic (A3C) [2] (but with a Q-value head), use the --on-policy option.
