We derived an optimal-order error estimate under a general source condition on, where is the initial approximation to the actual solution (signal) The choice of the regularization parameter is made according to the adaptive method considered by Pereverzev and Schock (2005). 2D visualization shows the effectiveness of the proposed method. © 2014 Springer India.Ill-posed problemsLavrentiev regularizationMonotone operatorNewton methodNonlinear analysis
