What are constraints?

Some articles on constraints, constraint:

Semi-infinite Programming
... number of variables and an infinite number of constraints, or an infinite number of variables and a finite number of constraints ... In the former case the constraints are typically parameterized ...
SQL Problems Requiring Cursors - Constraints
... In this article, the following constraints apply The term "cursor" includes all cursor-like behavior ...
Structured SVM - Separation
... The above quadratic program involves a very large, possibly infinite number of linear inequality constraints ... Instead the problem is solved by using delayed constraint generation where only a finite and small subset of the constraints is used ... Optimizing over a subset of the constraints enlarges the feasible set and will yield a solution which provides a lower bound on the objective ...

Famous quotes containing the word constraints:

    Play is a major avenue for learning to manage anxiety. It gives the child a safe space where she can experiment at will, suspending the rules and constraints of physical and social reality. In play, the child becomes master rather than subject.... Play allows the child to transcend passivity and to become the active doer of what happens around her.
    Alicia F. Lieberman (20th century)

    The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.
