Researchers have developed STEER2REACH (S2R), a new method for solving Hamilton-Jacobi (HJ) reachability problems. This approach utilizes physics-informed neural networks (PINNs) and addresses the computational complexity that has limited the practical application of HJ reachability. S2R employs an adaptive sampling distribution that steers forward trajectories using optimal control and disturbance signals, along with stochastic noise, to learn accurate safety value functions with minimal modification to standard PINNs training.
