Struct vrp_core::solver::termination::MinVariation

pub struct MinVariation { /* fields omitted */ }

A termination criteria which calculates coefficient variation in each objective and terminates when min threshold is not reached.

Implementations

impl MinVariation

pub fn new_with_sample(sample: usize, threshold: f64, is_global: bool) -> Self

Creates a new instance of MinVariation with sample interval type.

pub fn new_with_period(period: usize, threshold: f64, is_global: bool) -> Self

Creates a new instance of MinVariation with period interval type.

Trait Implementations

impl Termination for MinVariation

fn is_termination(&self, refinement_ctx: &mut RefinementContext) -> bool

Returns true if termination condition is met.

fn estimate(&self, _: &RefinementContext) -> f64

Returns a relative estimation till termination. Value is in the [0, 1] range.
