Defines how the solver should handle the request. In all modes but
VALIDATE_ONLY, if the request is invalid, you will receive an
INVALID_REQUEST error. See [max_validation_errors][google.cloud.optimization.v1.OptimizeToursRequest.max_validation_errors] to cap the number of
errors returned.
Only populates
[OptimizeToursResponse.skipped_shipments][google.cloud.optimization.v1.OptimizeToursResponse.skipped_shipments],
and doesn't actually solve the rest of the request (status and routes
are unset in the response).
IMPORTANT: not all infeasible shipments are returned here, but only the
ones that are detected as infeasible as a preprocessing.
ValidateOnly
Only validates the model without solving it: populates as many
[OptimizeToursResponse.validation_errors][google.cloud.optimization.v1.OptimizeToursResponse.validation_errors]
as possible.
