Struct vrp_core::construction::constraints::TourSizeModule

pub struct TourSizeModule { /* fields omitted */ }

Limits amount of job activities per tour.

Implementations

impl TourSizeModule

pub fn new(limit_func: TourSizeResolver, code: i32) -> Self

Creates a new instance of TourSizeModule.

Trait Implementations

impl ConstraintModule for TourSizeModule

fn accept_insertion(&self, _: &mut SolutionContext, _: usize, _: &Job)

Accept insertion of specific job into the route. Called once job has been inserted into solution represented via solution_ctx. Target route is defined by route_index which refers to routes collection in solution context. Inserted job is job. This method should call accept_route_state internally.

fn accept_route_state(&self, _: &mut RouteContext)

Accept route and updates its state to allow more efficient constraint checks.

fn accept_solution_state(&self, _: &mut SolutionContext)

Accepts insertion solution context allowing to update job insertion data. This method called twice: before insertion of all jobs starts and when it ends.

fn state_keys(&self) -> Iter<'_, i32>

Returns unique constraint state keys. Used to avoid state key interference.

fn get_constraints(&self) -> Iter<'_, ConstraintVariant>

Returns list of constraints to be used.
