Struct google_api_proto::google::cloud::optimization::v1::injected_solution_constraint::constraint_relaxation::Relaxation

pub struct Relaxation {
    pub level: i32,
    pub threshold_time: Option<Timestamp>,
    pub threshold_visit_count: i32,
}

If relaxations is empty, the start time and sequence of all visits on routes are fully constrained and no new visits may be inserted or added to those routes. Also, a vehicle’s start and end time in routes is fully constrained, unless the vehicle is empty (i.e., has no visits and has used_if_route_is_empty set to false in the model).

relaxations(i).level specifies the constraint relaxation level applied to a visit #j that satisfies:

• route.visits(j).start_time >= relaxations(i).threshold_time AND
• j + 1 >= relaxations(i).threshold_visit_count

Similarly, the vehicle start is relaxed to relaxations(i).level if it satisfies:

• vehicle_start_time >= relaxations(i).threshold_time AND
• relaxations(i).threshold_visit_count == 0 and the vehicle end is relaxed to relaxations(i).level if it satisfies:
• vehicle_end_time >= relaxations(i).threshold_time AND
• route.visits_size() + 1 >= relaxations(i).threshold_visit_count

To apply a relaxation level if a visit meets the threshold_visit_count OR the threshold_time add two relaxations with the same level: one with only threshold_visit_count set and the other with only threshold_time set. If a visit satisfies the conditions of multiple relaxations, the most relaxed level applies. As a result, from the vehicle start through the route visits in order to the vehicle end, the relaxation level becomes more relaxed: i.e., the relaxation level is non-decreasing as the route progresses.

The timing and sequence of route visits that do not satisfy the threshold conditions of any relaxations are fully constrained and no visits may be inserted into these sequences. Also, if a vehicle start or end does not satisfy the conditions of any relaxation the time is fixed, unless the vehicle is empty.

Fields

level: i32

The constraint relaxation level that applies when the conditions at or after threshold_time AND at least threshold_visit_count are satisfied.

threshold_time: Option<Timestamp>

The time at or after which the relaxation level may be applied.

threshold_visit_count: i32

The number of visits at or after which the relaxation level may be applied. If threshold_visit_count is 0 (or unset), the level may be applied directly at the vehicle start.

If it is route.visits_size() + 1, the level may only be applied to the vehicle end. If it is more than route.visits_size() + 1, level is not applied at all for that route.

Implementations

impl Relaxation

pub fn level(&self) -> Level

Returns the enum value of level, or the default if the field is set to an invalid enum value.

Sets level to the provided enum value.

Trait Implementations

Clears the message, resetting all fields to their default.

impl PartialEq for Relaxation

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
