A hybridization of the Polak-Ribière-Polyak and Fletcher-Reeves conjugate gradient methods
In order to achieve a theoretically effective and numerically efficient method for solving large-scale unconstrained optimization problems, a hybridization of the Fletcher-Reeves and Polak-Ribière-Polyak conjugate gradient methods is proposed...
A New Three–Term Conjugate Gradient Method with Descent Direction for Unconstrained Optimization
In this paper, we propose a three{term PRP{type conjugate gradient
method which always satisfies the sufficient descent condition independently of line
searches employed. An important property of our method ...
A new and fast correntropy-based method for system identification with exemplifications in low-SNR communications regime
One of the most significant issues in machine learning is system identification with many applications, e.g., channel estimation (CE) in digital communications. Introducing a new correntropy-based method, this paper deals ...
Estimating the heat source and the heat transfer coefficient simultaneously in a living tissue by conjugate gradient method
simultaneously. Both of these parameters are considered as
functions of time, and since no information exists about their
functional form, the problem is classified as the function
estimation method. Conjugate gradient method...
Two optimal Dai–Liao conjugate gradient methods
Two adaptive choices for the parameter of Dai–Liao conjugate gradient (CG) method are suggested. One of which is obtained by minimizing the distance between search directions of Dai–Liao method and a three-term CG method ...
Simultaneous estimation of controllable parameters in a living tissue during thermal therapy
time, and since no information exists about their functional form, the problem is classified as the
function estimation approach. Conjugate gradient method is applied as an inverse method. Two test
cases are considered and the effect of measurement...
A descent extension of the Polak–Ribière–Polyak conjugate gradient method
Based on an eigenvalue analysis, a descent class of two-parameter extension of the conjugate gradient method proposed by Polak and Ribière (1969), and Polyak (1969) is suggested.It is interesting that the one-parameter class of descent conjugate...
A descent hybrid modification of the Polak–Ribiere–Polyak conjugate gradient method
Hybridizing self-adjusting approach of Dong et al. and three-term formulation of Zhang et al., a nonlinear conjugate gradient method is proposed. The method reduces to the Polak–Ribière–Polyak method under the exact line search and satisfies...
Descent Symmetrization of the Dai–Liao Conjugate Gradient Method
Symmetrizing the Dai–Liao (DL) search direction matrix by a rank-one modification, we propose a one-parameter class of nonlinear conjugate gradient (CG) methods which includes the memoryless Broyden–Fletcher–Goldfarb–Shanno ...
