in this paper, a new analytical approach has been presented for solving strongly nonlinear oscillator problems. iteration perturbation method leads us to high accurate solution. two different high nonlinear examples are also presented to show the application and accuracy of the presented method. the results are compared with analytical methods and with the numerical solution using runge-kutta m...

The policy iteration method is a classical algorithm for solving optimal control problems. We introduce Mean Field Games systems and we prove, under monotonicity assumption on the coupling cost, convergence of this procedure to solution problem.
