Solving rank one revised linear systems by the scaled ABS method
Published online by Cambridge University Press: 17 February 2009
Abstract
In mathematical programming, an important tool is the use of active set strategies to update the current solution of a linear system after a rank one change in the constraint matrix. We show how to update the general solution of a linear system obtained by use of the scaled ABS method when the matrix coefficient is subjected to a rank one change.
