Query: Evaluating model-based planning and planner amortization for continuous
  control   There is a widespread intuition that model-based control methods should be
able to surpass the data efficiency of model-free approaches. In this paper we
attempt to evaluate this intuition on various challenging locomotion tasks. We
take a hybrid approach, combining model predictive control (MPC) with a learned
model and model-free policy learning; the learned policy serves as a proposal
for MPC. We find that well-tuned model-free agents are strong baselines even
for high DoF control problems but MPC with learned proposals and models
(trained on the fly or transferred from related tasks) can significantly
improve performance and data efficiency in hard multi-task/multi-goal settings.
Finally, we show that it is possible to distil a model-based planner into a
policy that amortizes the planning computation without any loss of performance.
