A Numerical Investigation of Ellipsoid Algorithms for Large-Scale Linear Programming.
TL;DR: In this paper, a variant of the ellipsoid update is developed, to take advantage of the range constraints that often occur in linear programs (i.e., constraints of the form l or = aTx or = u, where u - l is reasonably small).
Journal ArticleDOI
Trends in nonlinear programming software
TL;DR: This paper highlights selected key aspects of past and future optimization software, in the hope that potential users may become aware of significant advances.
A Procedure for Computing Forward-Difference Intervals for Numerical Optimization.
TL;DR: An algorithm for computing a set of intervals to be used in a forward-difference approximation of the gradient, and its implementation as a transportable Fortran subroutine is presented.
ReportDOI
On the Representation of a Basis for the Null Space.
TL;DR: In this paper, the authors discuss several aspects of the representation of a basis for the null space, and describe how an explicit matrix Z can be obtained at any point using a method for updating a factorization with either Householder or stabilized elementary transformations.
