>
> The parfor construct supports various optimizers, including a {{CONSTRAINED}}
> optimizer that that optimized around user-provided defaults. To do so it
> makes sure that these parameters are propagated down to the runtime, and
> marking all other paramters as unspecified, whereas for other optimizers
> (incl NONE) unspecified parameters are replaced with defaults.
> All parameters are supposed to be case-insensitive. However, if
> {{constrained}} instead of {{CONSTRAINED}} is used the unspecified parameters
> are replaced with default which look from the perspective of the constrained
> optimizer as user-provided input that cannot be changed.
