Query: Physical Reasoning Using Dynamics-Aware Models   A common approach to solving physical reasoning tasks is to train a value
learner on example tasks. A limitation of such an approach is that it requires
learning about object dynamics solely from reward values assigned to the final
state of a rollout of the environment. This study aims to address this
limitation by augmenting the reward value with self-supervised signals about
object dynamics. Specifically, we train the model to characterize the
similarity of two environment rollouts, jointly with predicting the outcome of
the reasoning task. This similarity can be defined as a distance measure
between the trajectory of objects in the two rollouts, or learned directly from
pixels using a contrastive formulation. Empirically, we find that this approach
leads to substantial performance improvements on the PHYRE benchmark for
physical reasoning (Bakhtin et al., 2019), establishing a new state-of-the-art.
