A matrix-free trust-region SQP algorithm for large-scale optimization

Coauthors: Miguel Aguilo, Joseph Young


We present an inexact trust-region sequential quadratic
programming (SQP) method for the matrix-free solution of
large-scale nonlinear programming problems. First, we
discuss recent algorithmic advances in the handling of
inequality constraints. Second, for optimization problems
governed by partial differential equations (PDEs) we
introduce a class of preconditioners for optimality
systems that are easily integrated into our matrix-free
trust-region framework and that efficiently reuse the
available PDE solvers. We conclude the presentation with
numerical examples in acoustic design, material inversion
in elastodynamics and optimization-based failure analysis.
