We investigate the method of asymptotical regularization for solving nonlinear illposed problems F(x) = y in Hilbert spaces. A general uniformly convex functional has been embedded in the evolution equations which is allowed to be non-smooth, thus the algorithm can be applied for sparsity and discontinuity reconstruction. Assuming certain conditions concerning the nonlinear operator F and functional Theta, we establish the convergence and stability of the method.
