Convergence Properties of Nonlinear Conjugate Gradient Methods

SIAM Journal on Optimization, 2000
The authors study a class of conjugate gradient-type methods \(x_{k+1}=x_k+\lambda_k d_k, d_k=-f''(x_k)+\beta_k d_{k-1}\) for the unconstrained minimization problem \(\min_{x \in R^n} f(x)\). Let \(f(x)\) be bounded below on \(L=\{x \in R^n: f(x) \leq f(x_1) \}\) and \(f''(x)\) be Lipschitz continuous on \(L\) where \(L\) may be unbounded. Suppose that

A new nonlinear conjugate gradient method

AIP Conference Proceedings, 2015
Conjugate gradient (CG) methods are essential for solving large-scale unconstrained optimization problems. Many of studies and modifications have been practiced to improve this method. In this paper, a new class of conjugate gradient coefficients (βk) with a new parameter m = ‖gk‖‖dk−1‖ that possess global convergence properties is presented.

Conjugate gradient method for adaptive nonlinear filtering

Proceedings of 1994 37th Midwest Symposium on Circuits and Systems, 2002
The application of the Conjugate Gradient (CG) method for the identification of a new class of non-linear discrete time systems, called "Generalized Bilinear System" is investigated. An algorithm based on the CG method is developed for adaptive generalized bilinear filtering with output error method.
