Struct vrp_core::construction::constraints::ConstraintPipeline

pub struct ConstraintPipeline { /* fields omitted */ }

Provides the way to work with multiple constraints.

Implementations

impl ConstraintPipeline

pub fn accept_insertion(
    &self,
    solution_ctx: &mut SolutionContext,
    route_index: usize,
    job: &Job
)

Accepts job insertion.

pub fn accept_route_state(&self, route_ctx: &mut RouteContext)

Accepts route state.

pub fn accept_solution_state(&self, solution_ctx: &mut SolutionContext)

Accepts solution state.

pub fn add_module(
    &mut self,
    module: Box<dyn ConstraintModule + Send + Sync>
) -> &mut Self

Adds constraint module.

pub fn evaluate_hard_route(
    &self,
    solution_ctx: &SolutionContext,
    route_ctx: &RouteContext,
    job: &Job
) -> Option<RouteConstraintViolation>

Checks whether all hard route constraints are fulfilled. Returns result of first failed constraint or empty value.

pub fn evaluate_hard_activity(
    &self,
    route_ctx: &RouteContext,
    activity_ctx: &ActivityContext<'_>
) -> Option<ActivityConstraintViolation>

Checks whether all activity route constraints are fulfilled. Returns result of first failed constraint or empty value.

pub fn evaluate_soft_route(
    &self,
    solution_ctx: &SolutionContext,
    route_ctx: &RouteContext,
    job: &Job
) -> Cost

Checks soft route constraints and aggregates associated actual and penalty costs.

pub fn evaluate_soft_activity(
    &self,
    route_ctx: &RouteContext,
    activity_ctx: &ActivityContext<'_>
) -> Cost

Checks soft route constraints and aggregates associated actual and penalty costs.
