GRBgettuneresult
| int | GRBgettuneresult ( | GRBmodel | *model, |
| int | n ) |
Use this routine to retrieve the results of a previous
GRBtunemodel call. Calling this
routine with argument n causes tuned parameter set n
to be copied into the model. Parameter sets are stored in order of
decreasing quality, with parameter set 0 being the best. The number
of available sets is stored in attribute
TuneResultCount.
Once you have retrieved a tuning result, you can call
GRBoptimize to use these parameter
settings to optimize the model, or
GRBwrite to write the changed
parameters to a .prm file.
Please refer to the parameter tuning section for details on the tuning tool.
Return value:
A non-zero return value indicates that a problem occurred while retrieving a tuning result. Refer to the Error Code table for a list of possible return values. Details on the error can be obtained by calling GRBgeterrormsg.
Arguments:
model: A model that has previously been used as the argument of GRBtunemodel.
n: The index of the tuning result to retrieve. The best result is available as index 0. The number of stored results is available in attribute TuneResultCount.
Example usage:
error = GRBtunemodel(model);
if (error) goto QUIT;
error = GRBgetintattr(model, "TuneResultCount", &nresults);
if (error) goto QUIT;
if (nresults > 0) {
error = GRBgettuneresult(model, 0);
if (error) goto QUIT;
}
