Name of the article On iterative methods for solving nonlinear least squares problems with operator decomposition
Abstract The iterative differential-difference methods for solving nonlinear least squares problems with decomposition of the operator are proposed and investigated. They use the sum of derivative of differentiable part of operator and divided difference of non-differentiable part of the operator instead the Jacobian. The local convergence of the proposed method under weak ω-conditions is justified and the rates of convergence are established. Numerical results are presented.
