Struct argmin::solver::trustregion::dogleg::Dogleg[][src]

pub struct Dogleg<F> { /* fields omitted */ }

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.
