LANS Informal Seminar
"Large-Scale Nonlinear Optimization with Inexact Step Computations"

DATE: December 7, 2011

TIME: 15:00:00 - 16:00:00
SPEAKER: Andreas Waechter, Northwestern University
LOCATION: Building 240, 1404-1405, Argonne National Laboratory

An algorithm for large-scale nonlinear nonconvex optimization is presented. Search directions are computed by an iterative linear solver, with termination criteria for the inexact solution ensuring global convergence under mild assumptions. The practical performance of the method is demonstrated on 3D PDE-constrained optimization examples.
