On the Hamilton-Jacobi-Bellman Equation by the Homotopy Perturbation Method
Abstract and Applied Analysis, 2014 Our concern in this paper is to use the homotopy decomposition method to solve the Hamilton-Jacobi-Bellman equation (HJB). The approach is obviously extremely well organized and is an influential procedure in obtaining the solutions of the equations.
