Constraints can be internal or external to the system. An internal constraint is in evidence when the market demands more from the system than it can deliver. If this is the case, then the focus of the organization should be on discovering that constraint and following the five focusing steps to open it up (and potentially remove it).
If the problem mandates that the constraints be satisfied, as in the above discussion, the constraints are sometimes referred to as hard constraints.However, in some problems, called flexible constraint satisfaction problems, it is preferred but not required that certain constraints be satisfied; such non-mandatory constraints are known as soft constraints.
The bucket elimination algorithm can be adapted for constraint optimization. A given variable can be indeed removed from the problem by replacing all soft constraints containing it with a new soft constraint. The cost of this new constraint is computed assuming a maximal value for every value of the removed variable.
"A social fact is any way of acting, whether fixed or not, capable of exerting over the individual an external constraint; or: which is general over the whole of a given society whilst having an existence of its own, independent of its individual manifestations." [1] He viewed it as a concrete idea that affected a person's everyday life. [3]
Constraint may refer to: Constraint (computer-aided design) , a demarcation of geometrical characteristics between two or more entities or solid modeling bodies Constraint (mathematics) , a condition of an optimization problem that the solution must satisfy
The concept can also include freedom from internal constraints on political action or speech such as social conformity, consistency, or inauthentic behaviour. [8] The concept of political freedom is closely connected with the concepts of civil liberties and human rights , which in democratic societies are usually afforded legal protection from ...
The objective of the system context diagram is to focus attention on external factors and events that should be considered in developing a complete set of systems requirements and constraints. System context diagrams are used early in a project to get agreement on the scope under investigation. [4]
Biological constraints are factors which make populations resistant to evolutionary change. One proposed definition of constraint is "A property of a trait that, although possibly adaptive in the environment in which it originally evolved, acts to place limits on the production of new phenotypic variants."
