Abstract: A restrictively preconditioned conjugate gradient method is presented for solving a large sparse system of linear equations. This new method originates from the classical conjugate gradient ...
Abstract: For the conjugate gradient method to solve the unconstrained optimization problem, given a new interval method to obtain the direction parameters, and a new conjugate gradient algorithm is ...
where \(f:R^n \rightarrow R\) is continuously differentiable. There are many methods for solving (1) such as quasi-Newton methods, Levenberg-Marquardt (LM) methods, and trust region methods. However, ...
This paper introduces two three-term trust region conjugate gradient algorithms, TT-TR-WP and TT-TR-CG, which are capable of converging under non-Lipschitz continuous gradient functions without any ...
