Constraint
81Budget constraint — A Budget constraint represents the combinations of goods and services that a consumer can purchase given current prices and his income. Consumer theory uses the concepts of a budget constraint and a preference map to analyze consumer choices.… …
82Carrier's constraint — is the observation that air breathing vertebrates which have two lungs and flex their bodies sideways during locomotion find it very difficult to move and breathe at the same time, because: *the sideways flexing expands one lung and compresses… …
83Primal constraint graph — In constraint satisfaction, the primal constraint graph or simply primal graph (also the Gaifman graph) of a constraint satisfaction problem is the graph whose nodes are the variables of the problem and an edge joins a pair of variables if the… …
84Object Constraint Language — The Object Constraint Language (OCL) is a declarative language for describing rules that apply to Unified Modeling Language (UML) models developed at IBM and now part of the UML standard. Initially, OCL was only a formal specification language… …
85Participation constraint (ER modelling) — A participation constraint in ER modelling may be understood as a special case of a multiplicity constraint. The participation constraint requires that an entity participates at least once in a relationship. The multiplicity constraint is… …
86Cash-in-advance constraint — The cash in advance constraint (sometimes known as the Clower constraint after American economist Robert Clower)[1] is an idea used in economic theory to capture monetary phenomena. In the most basic economic models (such as the Walras model or… …
87Natural Constraint Language — NCL (Natural Constraint Language) is a description language with mathematical logic as syntax. Il adopts Mixed Set Programming as algorithmic framework for modeling and solving problems. Introduction Combinatorial problems are ubiquitous in the… …
88Hamiltonian constraint — In loop quantum gravity, dynamics such as time evolutions of fields are controlled by the Hamiltonian constraint. The identity of the Hamiltonian constraint is a major open question in quantum gravity, as is extracting of physical observables… …
89Gauss' principle of least constraint — The principle of least constraint is another formulation of classical mechanics enunciated by Carl Friedrich Gauss in 1829.The principle of least constraint is a least squares principle stating that the true motion of a mechanical system of N… …
90Participation constraint — may refer to:* Participation constraint (ER modelling), in software engineering * Participation constraint (mechanism design), in economics …
