Struct Route 

pub struct Route {
    pub nodes: Vec<usize>,
}

Represents a single vehicle route servicing a sequence of customers.

The route implicitly starts at the depot (node 0) and ends at the depot (node 0). The nodes vector stores only the customer sequence (nodes >= 1).

Fields

nodes: Vec<usize>

Ordered sequence of customer indices visited by this vehicle.

Implementations

impl Route

pub fn new() -> Self

Creates a new empty route.

pub fn from_nodes(nodes: Vec<usize>) -> Self

Creates a route with a predefined sequence of customer nodes.

pub fn len(&self) -> usize

Returns the number of customers in this route.

pub fn is_empty(&self) -> bool

Returns true if the route contains no customers.

pub fn distance(&self, instance: &SolomonInstance) -> f32

Calculates the total euclidean distance traveled by the route: depot (0) -> nodes[0] -> ... -> nodes[n-1] -> depot (0). An empty route has a distance of 0.0.

pub fn total_demand(&self, instance: &SolomonInstance) -> f32

Calculates the total demand delivered to all customers in this route.

pub fn is_capacity_feasible(&self, instance: &SolomonInstance) -> bool

Returns true if the total route demand does not exceed vehicle capacity.

Trait Implementations

impl Clone for Route

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Route

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

Formats the value using the given formatter.

impl Default for Route

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Route

impl PartialEq for Route

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
