I noticed an error in the Unconstrained Optimization help page (see http://zone.ni.com/reference/en-XX/help/371361B-01/gmath/unconstrained_optimization/ for instance): the objective function template should be '...\ucno_objective function template.vit' instead of '...\cno_objective function template.vit'.
This missing 'u' drove me crasy for about 2 hours in understanding why I couldn't link my VI ref to the optimization VI 😞
