The curved nature of the approach places additional constraints upon the design.

The additional constraints of the face also allow more opportunities for using models and rules.

Without any additional constraints, the bridge wouldn't give all the information about the gauge field.

Such a mapping does not make sense without additional constraint.

The force and moment balances between the two bodies in contact act as additional constraints to the solution.

Such changes are always difficult to work through and additional constraints would be very frustrating for the association and its members.

Additional constraints on the employee's freedom could require this time to be compensated.

Additional constraints may be invoked to modify any specific permit.

In many applications, additional constraints such as limited resources or time windows make the problem considerably harder.
