must be respected in order to achieve useful results. Constraints to map generalisation …

In this paper the issue of reasoning about constraints is addressed. A design is derived
through the direct manipulation of constraints which narrow down the design space, and …

Towards an automated generalization workflow in cartography, the necessity and use of
constraints as means to control the whole process is widely recognized. There have been …

Software requirements describe a problem in the real world that a software system is
