CG Versus MINRES: An Empirical Comparison
Sultan Qaboos University Journal for Science, 2012 For iterative solution of symmetric systems the conjugate gradient method (CG) is commonly used when A is positive definite, while the minimum residual method (MINRES) is typically reserved for indefinite systems.

High-Resolution Source Localization Algorithm Based on the Conjugate Gradient
EURASIP Journal on Advances in Signal Processing, 2007 This paper proposes a new algorithm for the direction of arrival (DOA) estimation of P radiating sources. Unlike the classical subspace-based methods, it does not resort to the eigendecomposition of the covariance matrix of the received data. Indeed, the

Pricing stock loans under the L$ \acute{e} $vy-$ \alpha $-stable process with jumps
Networks and Heterogeneous Media, 2022 In this paper, the pricing of stock loans when the underlying follows a L$ \acute{e} $vy-$ \alpha $-stable process with jumps is considered. Under this complicated model, the stock loan value satisfies a fractional-partial-integro-differential equation ...

Large-scale wave-front reconstruction for adaptive optics systems by use of a recursive filtering algorithm [PDF]
, 2005 We propose a new recursive filtering algorithm for wave-front reconstruction in a large-scale adaptive optics system. An embedding step is used in this recursive filtering algorithm to permit fast methods to be used for wave-front reconstruction on an ...

Convergence behavior of single-step GBLUP and SNPBLUP for different termination criteria
Genetics Selection Evolution, 2021 Background The preconditioned conjugate gradient (PCG) method is the current method of choice for iterative solving of genetic evaluations. The relative difference between two successive iterates and the relative residual of the system of equations are ...
