batch_optimize_tours
batch_optimize_tours(request: Optional[Union[google.cloud.optimization_v1.types.fleet_routing.BatchOptimizeToursRequest, dict]] = None, *, retry: Union[google.api_core.retry.Retry, google.api_core.gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())Optimizes vehicle tours for one or more OptimizeToursRequest
messages as a batch.
This method is a Long Running Operation (LRO). The inputs for
optimization (OptimizeToursRequest messages) and outputs
(OptimizeToursResponse messages) are read/written from/to
Cloud Storage in user-specified format. Like the
OptimizeTours method, each OptimizeToursRequest contains
a ShipmentModel and returns an OptimizeToursResponse
containing ShipmentRoute\ s, which are a set of routes to be
performed by vehicles minimizing the overall cost.

get_mtls_endpoint_and_cert_source(
client_options: Optional[google.api_core.client_options.ClientOptions] = None,
)Return the API endpoint and client cert source for mutual TLS.
The client cert source is determined in the following order:
(1) if GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is not "true", the
client cert source is None.
(2) if client_options.client_cert_source is provided, use the provided one; if the
default client cert source exists, use the default one; otherwise the client cert
source is None.

default mTLS endpoint; if the environment variabel is "never", use the default API
endpoint; otherwise if client cert source exists, use the default mTLS endpoint, otherwise
use the default API endpoint.

optimize_tours
optimize_tours(request: Optional[Union[google.cloud.optimization_v1.types.fleet_routing.OptimizeToursRequest, dict]] = None, *, retry: Union[google.api_core.retry.Retry, google.api_core.gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Optional[float] = None, metadata: Sequence[Tuple[str, str]] = ())Sends an OptimizeToursRequest containing a ShipmentModel
and returns an OptimizeToursResponse containing
ShipmentRoute\ s, which are a set of routes to be performed
by vehicles minimizing the overall cost.
A ShipmentModel model consists mainly of Shipment\ s
that need to be carried out and Vehicle\ s that can be used
to transport the Shipment\ s. The ShipmentRoute\ s
assign Shipment\ s to Vehicle\ s. More specifically,
they assign a series of Visit\ s to each vehicle, where a
Visit corresponds to a VisitRequest, which is a pickup
or delivery for a Shipment.
The goal is to provide an assignment of ShipmentRoute\ s to
Vehicle\ s that minimizes the total cost where cost has many
components defined in the ShipmentModel.
