Approximate quasi-Newton methods

Mathematical Programming, 1990
Newton-like iterative methods for nonlinear equations on Banach spaces are considered. It is proved how the local convergence behaviour of the quasi-Newton method in the infinite dimensional setting is affected by the refinement strategy. Applications to boundary value problems and integral equations are included.

Quasi-Newton Updates with Bounds

SIAM Journal on Numerical Analysis, 1987
In each step of quasi-Newton methods an improved approximate solution \(x_ k\) is determined together with a new approximation \(B_ k\) of the derivative f'. Specifically, Broyden's method yields an update \(B_{k+1}\) which is the solution of the minimum problem: \(\min \{\| B-B_ k\|_ F: Bs_ k=y_ k\}.\) Here \(y_ k\) and \(s_ k\) are vectors which are ...

Quasi- Newton Methods for Nonlinear Equations

Journal of the ACM, 1968
A unified derivation is presented of the quasi-Newton methods for solving systems of nonlinear equations. The general algorithm contains, as special cases, all of the previously proposed quasi-Newton methods.

Quasi-Newton Methods

2008
In this chapter we take another approach toward the development of methods lying somewhere intermediate to steepest descent and Newton’s method. Again working under the assumption that evaluation and use of the Hessian matrix is impractical or costly, the idea underlying quasi-Newton methods is to use an approximation to the inverse Hessian in place of

Metodi Quasi-Newton

2011
Nel capitolo vengono descritti i metodi Quasi-Newton (noti anche come metodi tipo-secante o metodi a metrica variabile), che costituiscono una classe di metodi per la minimizzazione non vincolata basati sulla conoscenza delle derivate prime. Il piu noto dei metodi Quasi-Newton e il metodo BFGS, del quale analizziamo, nel caso convesso, le proprieta di ...

Quasi—Newton—Verfahren

1999
Dieses Kapitel behandelt die Klasse der sogenannten Quasi—Newton—Verfahren. Diese Verfahren verwenden anstelle der exakten Hesse—Matrix der zu minimierenden Funktion eine geeignete Approximation an diese (und vermeiden damit die haufig sehr aufwendige explizite Berechnung aller zweiten partiellen Ableitungen der Zielfunktion).
