spectral scaling structured BFGS methodIn this paper, we use a spectral scaled structured BFGS formula for approximating projected Hessian matrices in an exact penalty approach for solving constrained nonlinear least-squares problems. We show this spectral scaling formula has a good self-correcting ...
(2021) presented the two-parameter scaling memoryless Broyden–Fletcher–Goldfarb–Shanno (BFGS) method for solving a system of monotone nonlinear equations. A one-parameter memoryless Davidon–Fletcher–Powell (DFP) algorithm (Ullah et al. 2023) was introduced for solving a system of monotone ...
