Struct argmin::solver::trustregion::dogleg::Dogleg [−][src]
pub struct Dogleg<F> { /* fields omitted */ }
Expand description
The Dogleg method computes the intersection of the trust region boundary with a path given by the unconstraind minimum along the steepest descent direction and the optimum of the quadratic approximation of the cost function at the current point.
