in this paper, a vector version of the intermediate value theorem is established. the main theorem of this article can be considered as an improvement of the main results have been appeared in [textit{on fixed point theorems for monotone increasing vector valued mappings via scalarizing}, positivity, 19 (2) (2015) 333-340] with containing the uniqueness, convergent of each iteration to the fixe...

We present an overview of available software for solving linear programming problems using interior-point methods. Some of the codes discussed include primal and dual simplex solvers as well, but we focus the discussion on the implementation of the interior-point solver. For each solver, we present types of problems solved, available distribution modes, input formats and modeling languages, as ...

In this paper we present a redesign of a linear algebra kernel of an interior point method to avoid the explicit use of problem matrices. The only access to the original problem data needed are the matrix-vector multiplications with the Hessian and Jacobian matrices. Such a redesign requires the use of suitably preconditioned iterative methods and imposes restrictions on the way the preconditio...

3. page 13, lines 12–13: Insert a phrase to stress that we consider only monotone LCP in this book, though the qualifier ”monotone” is often omitted. Replace the sentence preceding the formula (1.21) by The monotone LCP—the qualifier ”monotone” is implicit throughout this book—is the problem of finding vectors x and s in I R that satisfy the following conditions: 4. page 13, line −12: delete “o...

This note provides a simpliied proof concerning the paper \A Primal-Dual Interior Point Method Whose Running Time Depends Only on the Constraint Matrix" by the same authors. In particular, we prove that Case II, one of the three cases in the method, can never occur.
