A Nonmonotone Conjugate Gradient Method for Nonlinear Optimization

2010 Third International Joint Conference on Computational Science and Optimization, 2010
In this paper, a no monotone conjugate gradient method for nonlinear optimization is proposed. Under weaker assumption on search direction dk and the mild assumptions on objective function f, the global convergence of the method is established.

New properties of a nonlinear conjugate gradient method

Numerische Mathematik, 2001
This paper provides several new properties of the nonlinear conjugate gradient method in by \textit{Y. H. Dai} and \textit{Y. Yuan} [SIAM J. Optim. 10, No.~1, 177-182 (1999; Zbl 0957.65061)]. Firstly , the method is proved to have a certain self adjusting property that is independent of the line search and the function convexity .

Convergence Analysis of Nonlinear Conjugate Gradient Methods

2010
Conjugate gradient methods are a class of important methods for unconstrained optimization and vary only with a scalar β k . In this chapter, we analyze general conjugate gradient method using the Wolfe line search and propose a condition on the scalar β k , which is sufficient for the global convergence.
