Extrapolated positive definite and positive semi-definite splitting methods for solving non-Hermitian positive definite linear systems [PDF]
summary:Recently, Na Huang and Changfeng Ma in (2016) proposed two kinds of typical practical choices of the PPS method. In this paper, we extrapolate two versions of the PPS iterative method, and we introduce the extrapolated Hermitian and skew ...

Adapting the interior point method for the solution of linear programs on high performance computers [PDF]
In this paper we describe a unified algorithmic framework for the interior point method (IPM) of solving Linear Programs (LPs) which allows us to adapt it over a range of high performance computer architectures. We set out the reasons as to why IPM makes

Optimal solution approximation for infinite positive-definite quadratic programming [PDF]
We consider a general doubly-infinite, positive-definite, quadratic programming problem. We show that the sequence of unique optimal solutions to the natural finite-dimensional subproblems strongly converges to the unique optimal solution.
