Trait vrp_core::construction::constraints::SoftActivityConstraint

pub trait SoftActivityConstraint {
    fn estimate_activity(
        &self, 
        route_ctx: &RouteContext, 
        activity_ctx: &ActivityContext<'_>
    ) -> Cost;
}

Specifies soft constraint which operates on activity level.

Required Methods

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

Estimates activity insertion in specific route leg. Returns non-zero penalty if constraint is violated: positive makes insertion less attractive, negative - more.
