Struct LineSearch 

pub struct LineSearch { /* private fields */ }

Configurations for line search. If you are indecisive for values, it is sufficient to use default().

Implementations

impl LineSearch

pub fn with_initial_step_size(self, initial_step_size: f64) -> Self

pub fn with_step_update_rate(self, step_update_rate: f64) -> Self

pub fn with_armijo_param(self, armijo_param: f64) -> Self

pub fn with_curvature_param(self, curvature_param: f64) -> Self

pub fn search( &self, fx_gfx: &dyn Fn(&[f64]) -> (f64, Vec<f64>), x: &[f64], direction: &[f64], ) -> f64

• fx_gfx: function to optimize. It must also return the gradients of each inputs.
• x: current input value
• direction: direction to search

Trait Implementations

impl Clone for LineSearch

fn clone(&self) -> LineSearch

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LineSearch

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LineSearch

fn default() -> Self

Returns the “default value” for a type.
