Methods

#allow_large_deadline_despite_interruption_risk

def allow_large_deadline_despite_interruption_risk() -> ::Boolean

Returns

• (::Boolean) — If this is set, then the request can have a deadline (see https://grpc.io/blog/deadlines) of up to 60 minutes. Otherwise, the maximum deadline is only 30 minutes. Note that long-lived requests have a significantly larger (but still small) risk of interruption.

#allow_large_deadline_despite_interruption_risk=

def allow_large_deadline_despite_interruption_risk=(value) -> ::Boolean

Parameter

• value (::Boolean) — If this is set, then the request can have a deadline (see https://grpc.io/blog/deadlines) of up to 60 minutes. Otherwise, the maximum deadline is only 30 minutes. Note that long-lived requests have a significantly larger (but still small) risk of interruption.

Returns

• (::Boolean) — If this is set, then the request can have a deadline (see https://grpc.io/blog/deadlines) of up to 60 minutes. Otherwise, the maximum deadline is only 30 minutes. Note that long-lived requests have a significantly larger (but still small) risk of interruption.

#consider_road_traffic

def consider_road_traffic() -> ::Boolean

Returns

• (::Boolean) — Consider traffic estimation in calculating ShipmentRoute fields Transition.travel_duration, Visit.start_time, and vehicle_end_time; in setting the ShipmentRoute.has_traffic_infeasibilities field, and in calculating the OptimizeToursResponse.total_cost field.

#geodesic_meters_per_second=

def geodesic_meters_per_second=(value) -> ::Float

#injected_first_solution_routes

def injected_first_solution_routes() -> ::Array<::Google::Cloud::Optimization::V1::ShipmentRoute>

Returns

• (::Array<::Google::Cloud::Optimization::V1::ShipmentRoute>) — Guide the optimization algorithm in finding a first solution that is similar to a previous solution.

  The model is constrained when the first solution is built. Any shipments not performed on a route are implicitly skipped in the first solution, but they may be performed in successive solutions.

  The solution must satisfy some basic validity assumptions:

  • for all routes, vehicle_index must be in range and not be duplicated.
  • for all visits, shipment_index and visit_request_index must be in range.
  • a shipment may only be referenced on one route.
  • the pickup of a pickup-delivery shipment must be performed before the delivery.
  • no more than one pickup alternative or delivery alternative of a shipment may be performed.
  • for all routes, times are increasing (i.e., vehicle_start_time <= visits[0].start_time <= visits[1].start_time ... <= vehicle_end_time).
  • a shipment may only be performed on a vehicle that is allowed. A vehicle is allowed if Shipment.allowed_vehicle_indices is empty or its vehicle_index is included in Shipment.allowed_vehicle_indices.

  If the injected solution is not feasible, a validation error is not necessarily returned and an error indicating infeasibility may be returned instead.

#injected_first_solution_routes=

#injected_solution_constraint

def injected_solution_constraint() -> ::Google::Cloud::Optimization::V1::InjectedSolutionConstraint

Returns

• (::Google::Cloud::Optimization::V1::InjectedSolutionConstraint) — Constrain the optimization algorithm to find a final solution that is similar to a previous solution. For example, this may be used to freeze portions of routes which have already been completed or which are to be completed but must not be modified.

  If the injected solution is not feasible, a validation error is not necessarily returned and an error indicating infeasibility may be returned instead.

#injected_solution_constraint=

def injected_solution_constraint=(value) -> ::Google::Cloud::Optimization::V1::InjectedSolutionConstraint

Parameter

• value (::Google::Cloud::Optimization::V1::InjectedSolutionConstraint) — Constrain the optimization algorithm to find a final solution that is similar to a previous solution. For example, this may be used to freeze portions of routes which have already been completed or which are to be completed but must not be modified.

  If the injected solution is not feasible, a validation error is not necessarily returned and an error indicating infeasibility may be returned instead.

#interpret_injected_solutions_using_labels

def interpret_injected_solutions_using_labels() -> ::Boolean

Returns

• (::Boolean) — If true:
  • uses ShipmentRoute.vehicle_label instead of vehicle_index to match routes in an injected solution with vehicles in the request; reuses the mapping of original ShipmentRoute.vehicle_index to new ShipmentRoute.vehicle_index to update ConstraintRelaxation.vehicle_indices if non-empty, but the mapping must be unambiguous (i.e., multiple ShipmentRoutes must not share the same original vehicle_index).
  • uses ShipmentRoute.Visit.shipment_label instead of shipment_index to match visits in an injected solution with shipments in the request;
  • uses SkippedShipment.label instead of SkippedShipment.index to match skipped shipments in the injected solution with request shipments.

  This interpretation applies to the injected_first_solution_routes, injected_solution_constraint, and refresh_details_routes fields. It can be used when shipment or vehicle indices in the request have changed since the solution was created, perhaps because shipments or vehicles have been removed from or added to the request.

  If true, labels in the following categories must appear at most once in their category:

  • Vehicle.label in the request;
  • Shipment.label in the request;
  • ShipmentRoute.vehicle_label in the injected solution;
  • SkippedShipment.label and ShipmentRoute.Visit.shipment_label in the injected solution (except pickup/delivery visit pairs, whose shipment_label must appear twice).

  If a vehicle_label in the injected solution does not correspond to a request vehicle, the corresponding route is removed from the solution along with its visits. If a shipment_label in the injected solution does not correspond to a request shipment, the corresponding visit is removed from the solution. If a SkippedShipment.label in the injected solution does not correspond to a request shipment, the SkippedShipment is removed from the solution.

  Removing route visits or entire routes from an injected solution may have an effect on the implied constraints, which may lead to change in solution, validation errors, or infeasibility.

  NOTE: The caller must ensure that each Vehicle.label (resp. Shipment.label) uniquely identifies a vehicle (resp. shipment) entity used across the two relevant requests: the past request that produced the OptimizeToursResponse used in the injected solution and the current request that includes the injected solution. The uniqueness checks described above are not enough to guarantee this requirement.
