AWhat changed
Implements vectorized rigid-body transformations and JAX-compiled environment/learning loops on accelerators, allowing many parallel simulated-control trials on the same device.
Scientific scope
Implements vectorized rigid-body transformations and JAX-compiled environment/learning loops on accelerators, allowing many parallel simulated-control trials on the same device. MuJoCo-like tasks are rebuilt and not numerically identical to MuJoCo, so speed/learning comparisons depend on engine/task differences. Differentiable approximate contact simulation is not certified exact physical dynamics or guaranteed reliable gradients through every contact event; reported training times are hardware/task-specific.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
