Struct optimization::FixedStepWidth

pub struct FixedStepWidth { /* fields omitted */ }

Uses a fixed step width γ in each iteration instead of performing an actual line search.

Methods

impl FixedStepWidth

fn new(fixed_step_width: f64) -> FixedStepWidth

Creates a new FixedStepWidth given the static step width.

Trait Implementations

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Copy for FixedStepWidth

impl Clone for FixedStepWidth

Returns a copy of the value.

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

Performs copy-assignment from source.

impl LineSearch for FixedStepWidth

fn search<F>(
    &self,
    _function: &F,
    initial_position: &[f64],
    direction: &[f64]
) -> Vec<f64> where
    F: Function,
