Struct argmin::solver::trustregion::trustregion_method::TrustRegion [−][src]
pub struct TrustRegion<R, F> { /* fields omitted */ }
Expand description
The trust region method approximates the cost function within a certain region around the current point in parameter space. Depending on the quality of this approximation, the region is either expanded or contracted.
The calculation of the actual step length and direction is done by one of the following methods:
This subproblem can be set via set_subproblem(...)
. If this is not provided, it will default
to the Steihaug method.
