QN-like variable storage conjugate gradients
Mathematical Programming, 1983Both 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, 2015The 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.
