Randomized inexact block triangular preconditioners for double saddle-point systems in PDE-constrained optimization
Siqi Liang, Na Huang
We develop a new class of inexact block triangular preconditioners for double saddle-point systems arising from PDE-constrained optimization. The proposed preconditioners are const…

An inexact augmented Lagrangian algorithm for unsymmetric saddle-point systems
N. Huang, Y. -H. Dai, D. Orban +1
Augmented Lagrangian (AL) methods are a well known class of algorithms for solving constrained optimization problems. They have been extended to the solution of saddle-point system…
