Researchers have developed a new framework that combines dynamic programming with physics-informed neural networks (PINNs) to solve complex mathematical equations known as Hamilton--Jacobi--Isaacs (HJI) equations. This method is designed to handle high-dimensional and nonconvex HJI equations, which are crucial in areas like stochastic differential games and robust control. The proposed approach alternates between solving linear partial differential equations and updating control policies using automatic differentiation, demonstrating provable stability and convergence. Numerical experiments show the method's accuracy and scalability, outperforming direct PINN solvers in certain applications and showing potential for use in robotics, finance, and multi-agent reinforcement learning.
