Abstract
The content discusses a novel optimization-based approach utilizing the preconditioned primal-dual hybrid gradient method to address optimal control problems and Hamilton-Jacobi partial differential equations. The method reformulates these problems into a saddle point problem, enabling efficient solutions with first-order accuracy and numerical stability. The framework extends to viscous HJ PDEs and stochastic optimal control problems, showcasing versatility in managing diverse Hamiltonians. Through numerical examples, the effectiveness of the method is demonstrated in handling various scenarios, highlighting its potential for broad applications.
