Their proper modifications allow a significant acceleration of these schemes when the objective function has favorable properties (smoothness, strong convexity).

In this regard, we obtain regularized approximations by solving some non linear integral equations which is derived by considering a truncated version of the Fourier expansion of the sought solution. Under different Gevrey smoothness assumptions on the exact solution, we provide parameter choice strategies and obtain the error estimates.
