An inductive algorithm is presented for smooth approximation of functions based on the Tikhonov regularization, applied for specific kind of the Tikhonov parametric functional. The discrepancy principle is used for estimation of the regularization parameter. The principle of heuristic self-organization is applied for assessment of optimal values of some parameters.
