Which of the following statements is correct regarding model-based learning (multiple answers may apply)

		The dynamics model has to be provided in order to enable model-based approaches to operate. It cannot be learned
		The Model predictive control (MPC) variant of model-based learning both re plans the actions and updates the dynamics model throughout the trajectory
		It is possible both learn the dynamics model and update the policy at the same time
		Because we build a model of the dynamics (and therefore representing the world of the problem), overfitting is not a problem
