Scaled Diagonal Gradient-Type Method with Extra Update for Large-Scale Unconstrained Optimization
We present a new gradient method that uses scaling and extra updating within the diagonal updating for solving unconstrained optimization problem. The new method is in the frame of Barzilai and Borwein (BB) method, except that the Hessian matrix is approximated by a diagonal matrix rather than the m...
