Struct vrp_core::models::Goal

pub struct Goal { /* private fields */ }

Specifies a goal of optimization as a list of Feature objectives with rules in lexicographical order.

Implementations

impl Goal

pub fn simple(features: &[Feature]) -> GenericResult<Self>

Creates a goal using objectives from given list of features in lexicographical order. See GoalBuilder for more complex options.

pub fn subset_of<S: AsRef<str>>( features: &[Feature], names: &[S], ) -> GenericResult<Self>

Creates a goal using feature names from the given list. Objectives are defined in lexicographical order.

impl Goal

pub fn total_order( &self, a: &InsertionContext, b: &InsertionContext, ) -> Ordering

Compares two solutions from optimization goal point of view and returns their comparison order.

pub fn estimate(&self, move_ctx: &MoveContext<'_>) -> InsertionCost

Estimates insertion cost (penalty) of the refinement move.

pub fn fitness<'a>( &'a self, solution: &'a InsertionContext, ) -> impl Iterator<Item = f64> + 'a

Calculates solution’s fitness.

Trait Implementations

impl Clone for Goal

fn clone(&self) -> Goal

Returns a copy of the value.

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

Performs copy-assignment from source.
