Abstract

‎Nonlinear least-squares (NLS) problems find extensive applications across various fields within the applied sciences‎. ‎Conventional methods for solving NLS problems often face challenges related to computational efficiency and memory requirements‎, ‎especially when dealing with large-scale systems‎. ‎In this paper‎, ‎the solution to the minimization of nonlinear least squares problems has been obtained using a proposed structured accelerated three-term conjugate gradient method‎, ‎in which from Taylor series approximations of the objective function's Hessian‎, ‎the structured vector approximation involving a vector's action on a matrix is obtained‎. ‎This ensures the satisfaction of a quasi-Newton condition‎. ‎The technique then employs the structured vector approximation to incorporate additional information from the Hessian of the goal function into the standardized search direction‎. ‎The proposed method's search direction fulfills the necessary descent criterion‎. ‎Additionally‎, ‎numerical tests performed on various test problems show that the suggested approach is remarkably efficient‎, ‎surpassing some existing competitors‎.
