نویسندگان
چکیده
This letter simplifies and analyze existing state evolution recursions for conjugate gradient. The proposed simplification reduces the complexity solving from cubic order to square in total number of iterations. simplified are still catastrophically sensitive numerical errors, so that arbitrary-precision arithmetic is used accurate evaluation recursions.

Accurate conjugate gradient methods for shifted systems
We present an efficient and accurate variant of the conjugate gradient method for solving families of shifted systems. In particular we are interested in shifted systems that occur in Tikhonov regularization for inverse problems since these problems can be sensitive to roundoff errors. The success of our method in achieving accurate approximations is supported by theoretical arguments as well a...
متن کاملImplementation of Conjugate Gradient Algorithms
We evaluate the High-Performance Fortran (HPF) language for the compact expression and eecient implementation of conjugate gradient iterative matrix-solvers on High Performance Computing and Communi-cations(HPCC) platforms. We discuss the use of intrinsic functions, data distribution directives and explicitly parallel constructs to optimize performance by minimizing communications requirements ...

متن کاملA conjugate gradient based method for Decision Neural Network training
Decision Neural Network is a new approach for solving multi-objective decision-making problems based on artificial neural networks. Using inaccurate evaluation data, network training has improved and the number of educational data sets has decreased. The available training method is based on the gradient decent method (BP). One of its limitations is related to its convergence speed. Therefore,...
