In specific scenarios, system allows user to define what parameter values can never be tested together or in the other hand, scenarios where parameter values can only be tested together.
For that, user can apply constraints to support these cases.
So that the model can understand the requirements, you have the option to define invalid constraints (values that can never be tested together), and/or bound constraints (values that can only be tested together) to train the model.
Invalid constraints
Invalid constraints restrict parameter values that can never be tested together.

As you use the Invalid Pair feature and the related Bound Pair one, keep in mind these usage tips:

Do you need to add a lot of Invalid Constraints?
Watch out for “Not Applicable” Values.

Bound constraints
Bound constraints restrict parameter values that can only be tested together.

Lastly, you can do a quick review of available options & syntax by clicking the “Usage” button in top-right section of the Advanced Mode:

Edit a Constraint
To edit a constraint, you need to change view to "bulk" . Then you can edit the constrain type selecting the corresponding operator.
It is not possible to edit a constrain at the Standard View. In the Standard View you are only allowed to delete and create a new constrain.
Delete a Constraint
To delete a constraint, hover the constraint and select the delete option:
Another option is to, on bulk view mode, delete the desired constraint line:
