Compulsion implies the exertion of some urgent impelling force; as, driven by compulsion. The former prevents us from acting agreeably to our wishes; the latter forces us to act contrary to our will.

Wikipedia
Constraint

A constraint is something that plays the part of a physical, social or financial restriction. It is a derived form of the intransitive verb form constrained.

Constraint may refer to:

  • Theory of constraints, in business management
  • Loading gauge or structure gauge (constraints in engineering)
  • A constraint on constrained writing, in literature
    • For example, Oulipian constraints
Constraint (mathematics)

In mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. There are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. The set of candidate solutions that satisfy all constraints is called the feasible set.

Constraint (information theory)

Constraint in information theory refers to the degree of statistical dependence between or among variables.

Garner provides a thorough discussion of various forms of constraint (internal constraint, external constraint, total constraint) with application to pattern recognition and psychology.

Constraint (classical mechanics)

In classical mechanics, a constraint is a relation between coordinates and momenta (and possibly higher derivatives of the coordinates). In other words, a constraint is a restriction on the freedom of movement of a system of particles.

Constraint (computer-aided design)

In engineering design, particularly in the use of computer-aided drafting and design, in the creation of 3D assemblies and multibody systems, the plural term "constraints" refers to demarcations of geometrical characteristics between two or more entities or solid modeling bodies; these delimiters are intentional in defining diverse properties of theoretical physical position and motion, or displacement. In addition, 2D sketches -including the ones used to create extrusions and solid bodies- can also be constrained.

There are several constraints that may be applied between the entities or bodies depending much on their actual natural geometry; sometimes these are also referred to as ’’mates’’ and include: collinearity, perpendicularity, tangency, symmetry, coincidency and parallelity among other ways of establishing the orientation of the entity. Also, a constraint on two (or more) lines may be added so these are equal in length; in the same manner, the diameter of circles can be set to have the same dimension. Moreover, a solid model can also be set to be locked or fixed in space. Depending on the program, the terminology used in the application may differ.

The purpose of constraints in a design is to control and limit the behavior of the entities and bodies in relation to another entity, plane or body. Effective constraints or mates between two or more bodies may exist at the assembly level of these or between two or more entities in defining a sketch, but adding conflicting, unnecessary or redundant constraints may result in an overdefined sketch and an error message.

Usage examples of "constraint".
