QN-like variable storage conjugate gradients

Mathematical Programming, 1983
Both conjugate gradient and quasi-Newton methods are quite successful at minimizing smooth nonlinear functions of several variables, and each has its advantages. In particular, conjugate gradient methods require much less storage to implement than a quasi-Newton code and therefore find application when storage limitations occur.

Error bounds for linear complementarity problems of QN-matrices

Calcolo, 2015
The authors present error bounds of the linear complementarity problem when the involved matrix is a \(QN\)-matrix with positive diagonals. The results are illustrated with numerical examples.
