Abstract
The properties of multilevel optimization problems defined on a
hierarchy of discretization grids can be used to define approximate
secant equations, which describe the second-order behaviour of the
objective function. Following earlier work by Gratton and Toint
(2009), we introduce a quasi-Newton method (with a linesearch) and a
nonlinear conjugate gradient method that both take advantage of this
new second-order information. We then present numerical experiments
with these methods and formulate recommendations for their practical
use.
