Specification

Alias: none

Argument(s): none

Default: Function value labels optional

Description

The labeled keyword directs Dakota to enforce a stricter results file format and enables more detailed error reporting.

When the labeled keyword is used, function values in results files must be accompanied by their corresponding descriptors. If the user did not supply response descriptors in her Dakota input file, then Dakota auto-generated descriptors are expected.

Distinct error messages are emitted for function values that are out-of-order, repeated, or missing. Labels that appear without a function value and unexpected data are also reported as errors. Dakota attempts to report all errors in a results file, not just the first it encounters. After reporting results file errors, Dakota aborts.

Labels for analytic gradients and Hessians currently are not supported.

Although the labeled keyword is optional, its use is recommended to help catch and identify problems with results files. The User's Manual contains further information about the results file format.

Default Behavior

By default, Dakota does not require labels for function values, and ignores them if they are present.
