A constraint is a limitation of possibilities.
Mathematics In mathematics, a constraint is a restriction of the feasible solutions in an optimization problem. Euclid, detail from The School of Athens by Raphael. ...
In mathematics, the term optimization refers to the study of problems that have the form Given: a function f : A R from some set A to the real numbers Sought: an element x0 in A such that f(x0) ≤ f(x) for all x in A (minimization) or such that...
Theory of constraints In the theory of constraints, it is any factor that limits the performance of a system with respect to its goal. In a for-profit business, this would be the factors that limit the ability to make money. Theory of constraints (TOC) is a body of knowledge on the effective management of (mainly business) organizations, as systems. ...

To take a simple example: a chain has 5 links, each link capable of holding a maximum weight of 5, 7, 4, 8 and 6 tonnes respectively. The maximum weight the chain can hold is clearly 4 tonnes – the limit imposed by the weakest link. In this case, all 5 links have limits to their strength, but the 3rd link is the constraint because it is the greatest restriction on the system.

- at least one constraint, otherwise its performance would be infinite
- very few constraints, otherwise it would be unstable and cease to exist
Constraints are physical or systemic limits on capacity (such as equipment, people, new product development, "the market"). In the past, TOC experts talked about "policy constraints," but these are no longer considered to be true constraints. Policies and behaviors are barriers to be overcome when implementing changes, they are not constraints.
The concept of constraint is the basis for Goldratt's process of focused improvement. Focused improvement in theory of constraints is the ensemble of activities aimed at elevating the performance of any system, especially a business system, with respect to its goal by eliminating its constraints one by one and by not working on non-constraints. ...

Literature is literally acquaintance with letters as in the first sense given in the Oxford English Dictionary (from the Latin littera meaning an individual written character (letter)). The term has generally come to identify a collection of texts, which in Western culture are mainly prose, both fiction and non-fiction...
