int GRBoptimizebatch ( GRBmodel *model,
    char *BatchID )

Submit a new batch request to the Cluster Manager. Returns the BatchID (a string), which uniquely identifies the job in the Cluster Manager and can be used to query the status of this request (from this program or from any other). Once the request has completed, the BatchID can also be used to retrieve the associated solution. To submit a batch request, you must tag at least one element of the model by setting one of the VTag, CTag or QCTag attributes. For more details on batch optimization, please refer to the Batch Optimization section.

Note that this routine will process all pending model modifications.

Return value:

A non-zero return value indicates that a problem occurred while submit a batch request. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.


model: The model to optimize in batch mode. Note that this routine only reports whether the batch request ran into an error.

BatchID: On success, the location in which the BatchID of the newly created batch request should be stored. The pointer must point to a string of length GRB_MAX_STRLEN+1 or more.

Example usage:

  /* submit batch request to the Manager */
  error = GRBoptimizebatch(model, BatchID);
  if (error) goto QUIT;
