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 from and written to Cloud Storage in user-specified format. Like the locations.optimizeTours method, each OptimizeToursRequest contains a ShipmentModel and returns an OptimizeToursResponse containing ShipmentRoute fields, which are a set of routes to be performed by vehicles minimizing the overall cost.
The user can poll operations.get to check the status of the LRO:
If the LRO done field is false, then at least one request is still being processed. Other requests may have completed successfully and their results are available in Cloud Storage.
If the LRO's done field is true, then all requests have been processed. Any successfully processed requests will have their results available in Cloud Storage. Any requests that failed will not have their results available in Cloud Storage. If the LRO's error field is set, then it contains the error from one of the failed requests.
