Trait argmin::prelude::ArgminTrustRegion

pub trait ArgminTrustRegion: ArgminSolver {
    fn set_radius(&mut self, radius: f64);
    fn set_grad(&mut self, grad: Self::Param);
    fn set_hessian(&mut self, hessian: Self::Hessian);
}

Defines a common interface to methods which calculate approximate steps for trust region methods. Requires that ArgminSolver is implemented as well.

Required methods

fn set_radius(&mut self, radius: f64)

Set the initial step length

fn set_grad(&mut self, grad: Self::Param)

Set the gradient at the starting point

fn set_hessian(&mut self, hessian: Self::Hessian)

Set the gradient at the starting point
