Flow-aware Optimal Navigation in Unsteady Flows through Reinforcement Learning

A reinforcement learning approach using the TD3 algorithm to train autonomous agents to reach arbitrary targets within a parametric, chaotic double-gyre flow is presented and a trade-off in sensor utility is revealed: velocity-aware agents optimize energy efficiency, whereas vorticity sensors provide superior structural mapping and achieve better target proximity.

Physics-enhanced reinforcement learning for real-time optimal control of dynamical systems

PEARL employs an actor-adjoint algorithm that leverages automatic differentiation to compute policy gradients over short horizons and adjoint-based sensitivities of future returns approximated via neural networks, significantly reducing the number of environment interactions, while mitigating long-term gradient instabilities.
