The Conjugate Residual Method for Constrained Minimization Problems [PDF]
SIAM Journal on Numerical Analysis, 1970 The method of conjugate gradients, a particular version of the general class of conjugate direction methods, was originally developed for solving a linear system of equations$$ Ax = b,$$where $A$ is an $n \times n$ symmetric, positive definite matrix, $x$ is an unknown $n$-vector and $b$ is a fixed $n$-vector.

Solving Some Large Scale Semidefinite Programs via the Conjugate Residual Method
SIAM Journal on Optimization, 2002 Summary: Most current implementations of interior-point methods for semidefinite programming use a direct method to solve the Schur Complement Equation (SCE) \(M \Delta y=h\) in computing the search direction. When the number of constraints is large, the problem of having insufficient memory to store \(M\) can be avoided if an iterative method is used ...

Generalized Conjugate A-Orthogonal Residual Squared Method for Complex Non-Hermitian Linear Systems
Journal of Computational Mathematics, 2014 Recently numerous numerical experiments on realistic calculation have shown that the conjugate A-orthogonal residual squared (CORS) method is often competitive with other popular methods. However, the CORS method, like the CGS method, shows irregular convergence, especially appears large intermediate residual norm, which may lead to worse approximate ...
