SUMMARY:Approaches to accelerate methods for solving systems of equations
arising in nonlinear optimization
DESCRIPTION:In this pre-defense seminar\, I will present selected parts o
f my upcoming thesis. Methods for solving nonlinear optimization problem
s typically involve solving systems of equations. The thesis concerns ap
proaches for accelerating some of those methods. In our setting\, accele
rating involves finding a trade-off between the computational cost of an
iteration and the quality of the computed search direction. We have des
igned approaches for which theoretical results in ideal settings have be
en derived. We have also investigated the practical performance of the a
pproaches within and beyond the boundaries of the theoretical frameworks
with numerical simulations. \nThe initial part concerns solving strictl
y convex unconstrained quadratic optimization problems. In particular\,
exact linesearch limited-memory quasi-Newton methods which generate sear
ch directions parallel to those of the method of preconditioned conjugat
e gradients. The focus of the second part is approaches to accelerate pr
imal-dual interior-point methods. In particular\, approaches when the me
thod is applied to bound-constrained nonlinear optimization problems and
on quadratic optimization problems with linear inequality constraints.
