An application of conjugate gradient method under strong Wolfe line search for solving unconstrained optimization
TL;DR: This paper proposes a CG method with sufficient descent property under strong Wolfe line search and shows that the proposed CG formula has better performance than the other tested CG methods.
On the convergence of the Neumann series for electrostatic fracture response
TL;DR: The feasibility of Neumann-series expansion of Maxwell's equations in the electrostatic limit was investigated for potentially rapid and approximate subsurface imaging of geologic features in this paper, where the Neumann series expansion was applied to the geologic feature detection problem.

A Description of Preferential Sites for Vacancy Formation on Grain Boundaries in Copper by Structural Unit Model
TL;DR: In this paper, the preferential sites for vacancies on a series of symmetric tilt grain boundaries in copper have been investigated by molecular dynamics simulation, and the regularity of preferential sites on these boundaries can be described by the structural unit model.

Methods of Conjugate Gradients for Solving Linear Systems
TL;DR: An iterative algorithm is given for solving a system Ax=k of n linear equations in n unknowns and it is shown that this method is a special case of a very general method which also includes Gaussian elimination.
A Rapidly Convergent Descent Method for Minimization
Roger Fletcher,M. J. D. Powell +1 more
TL;DR: A number of theorems are proved to show that it always converges and that it converges rapidly, and this method has been used to solve a system of one hundred non-linear simultaneous equations.
