Curvature-based multistep quasi-Newton method for unconstrained optimization

Obeid, Samir; Moghrabi, I.A.R. (2016-02-02)

Multi-step methods derived in [1–3] have proven to be serious contenders in practice by outperforming traditional quasi-Newton methods based on the linear Secant Equation. Minimum curvature methods that aim at tuning the ...
A general model for minimum curvature quasi-Newton methods

Obeid, Samir; Moghrabi, I.A.R. (2016-02-02)
A new family of multi-step quasi-Newton algorithms for unconstrained optimization

Obeid, Samir; Moghrabi, I.A.R. (2015-11-27)

This work aims at ensuring smoothness of interpolation in both the iterate and the gradient spaces in the so-called multi-step quasi-Newton methods. It concentrates on deriving a variable-metric family of minimum curvature ...
A new minimum curvator multi-step method for unconstrained optimization

Obeid, Samir; Moghrabi, I.A.R. (2018-06-20)

Multistep quasi-Newton methods for optimization were derived by J. A. Ford and I. A. Moghrabi [J. Comput. Appl. Math. 50, No. 1-3, 305-323 (1994; Zbl 0807.65062)], where it was shown how an interpolation in the variable-space ...
