Struct vrp_core::utils::Noise

pub struct Noise { /* private fields */ }

Provides way to generate some noise to floating point value.

Implementations

impl Noise

pub fn new_with_addition( probability: f64, range: (f64, f64), random: Arc<dyn Random + Sync + Send, Global> ) -> Noise

Creates a new instance of Noise which will add some noise in given range to the target value: value = value + value * sample_from(range)

pub fn new_with_ratio( probability: f64, range: (f64, f64), random: Arc<dyn Random + Sync + Send, Global> ) -> Noise

Creates a new instance of Noise which will apply noise by multiplying target value by value from given range: value = value * sample_from(range)

pub fn generate_multi<'a, Iter>( &'a self, values: Iter ) -> impl Iterator<Item = f64> + 'awhere Iter: Iterator<Item = f64> + 'a,

Generates an iterator with noise.

pub fn generate(&self, value: f64) -> f64

Generate some noise based on given value.

pub fn random(&self) -> &(dyn Random + Sync + Send)

Returns random generator.

Trait Implementations

impl Clone for Noise

fn clone(&self) -> Noise

Returns a copy of the value.

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

Performs copy-assignment from source.
