Mandatory constraint
| Глоссарий ИТ-терминов |
A constraint that requires every instance of an object type’s population to play that role. with a disjunctive mandatory role constraint, each member of the object type’s population must play at least one of the roles indicated.

Constraint, английский
- Сдерживание (отношение события к последующей работе, из-за которого работа не может быть начата; отношение работы к последующему событию, из-за которого это событие не может совершиться)
- N 1 ограничение (син. restriction); 2 то же, что и cognitive principle functional head c~ уис один из принципов универсальной грамматики, согласно кото- рому фунциональная вершина требует нали- чия определенных признаков у своих ком- плементов 1 рассматриваемые в логике утвердительные выражения. mental ~s умственные ограничения
- The difference between a set and a subset indicating that the variety that exists under one condition is less than the variety that exists under another (after ashby). for an observer, constraints become apparent when he finds that a system can assume fewer states than are logically possible or hypothesised by him. within a cartesian product a constraint is the complement of a relation, the former contains all states excluded by the latter. information is a measure of the constraint imposed by a condition or message.
- A limitation or a restriction.
- Сдерживающий фактор
- Any restriction that occurs to the transverse contraction normally associated with a longitudinal tension, and that hence causes a secondary tension in the transverse direction.
Constraint analysis, английский
A formal method for decomposing the constraint within a whole system into several constraint within subsets of its variables, (i.e., of an ordinality lower than the original) so that the latter fully accounts for the former. constraint analysis thereby reveals the component structure of an observed system. the method, developed by ashby who stated it in set theoretical and hence qualitative terms, is now also known by the name reconstructability analysis and stated in probabilistic and hence quantitative terms (->information theory). 17

Constraint propagation, английский
Many systems have a series of constraints on the values or properties. if these can be represented by a network of relationships, the systems can propagate the local constraints throughout the system to achieve global consistency. generally, when a stable system is updated with new data or a query, the constraints can be iteratively fired to cascade through the system until the values of the system reach a stable state. see also: relaxation procedures.
Constraint reasoning, английский
See: constraint satisfaction.
Constraint satisfaction, английский
A general term for a variety of techniques used in ai and other areas of computation. constraint solving systems work with a knowledge base of constraints and include an engine to search for solutions that meet these constraints. a constraint solving system will cycle through the constraints, changing the free values in the system to meet some maximization or minimization criteria.
Constraint service, английский
A service responsible for answering hws constraints-related querying by evaluating constraint clauses that are based on facts provided by the fact store manager and the relevant fact retrievers.

Constraint violation, английский
- Невыполнение (заданного) ограничения (при адаптивном управлении станком, напр., превышение уставки силового параметра)
- A violation that occurs when the restriction criteria are not satisfied.
Constraint-based configuration, английский
A configuration technology that uses constraints to develop product masters and to configure distinct products.

Population, английский
- A definable set of individual units to which the findings from statistical examination of a sample subset are intended to be applied. the population will generally much outnumber the sample. in re-randomisation statistics the process of applying inference
- See stock.
- A collection of units being studied. units can be people, places, objects, epochs, drugs, procedures, or many other things. much of statistics is concerned with estimating numerical properties (parameters) of an entire population from a random sample of units from the population.
- A group or number of people living within a specified area or sharing similar characteristics (such as occupation or age).
- Население; народонаселение; генеральная совокупность (в выборочном наблюдении); популяция (биол)
- Население
- 1. the number of people living in a country or town population statistics show that the birth rate is slowing down. the government has decided to screen the whole population of the area. 2. the number of patients in hospital the hospital population in the area has fallen below 10,000.
- Популяция
- Население; популяция -
- Популяция. в клинических исследованиях совокупность субъектов, обладающих какими-либо одинаковыми признаками (пол, возраст, диагноз).
- Население; популяция
- Any group of individuals, usually of a single species, occupying a given area at the same time; groups of organisms with homologue (same) alleles. p. cycle: changes in the numbers of individuals in a population which repeatedly oscillate between periods of high and low density. p. density: allowing a mathematically precise reflection - pd. • absolute: pd = number of individuals/unit area or volume [1/m2] or [1/m3] • relative: pd allows only a simple comparison (pd <, =, >, ? etc.). p. dynamics: the variations in time and space in the sizes and densities of populations; distribution due to changing food resources - the stability of a population depends upon abiotic factors, intraspecific competition (density dependent), natality, mortality etc. p. ecology: the study of the variations in time and space in the sizes and densities of populations, and of the factors causing those variations. p. fluctuation: variations over time in the size of a population. p. growth: is zero, when the birth rate equals the death rate (see carrying capacity). nt+1 = nt + r nt, current number of individuals r = (natality + immigration) - (mortality+emigration) r, intrinsic rate of growth (see density) p. pyramid: a means of illustrating the age structure of a population diagrammatically, by placing the youngest age class at the base and stacking successive age classes above it. p. regulation : a tendency in a population for some factor to cause density to increase when it is low and to decrease nt, momentary number of individuals when it is high. n0, number of individuals at start
- Generally, a collection of individuals with common characteristics. in statistics, a potentially infinite collection of independent (->independence) units that include all units of a specified type with attention paid only to the agggregate (->aggregation) property of the collection. a sample of data drawn from this population is a subset of the units constituting this population and scientific generalizations from such samples are limited by the size of the population originally specified (->model, ->representation).
- The process of scanning content to compile and maintain an index.
- Fish of the same species inhabiting a specified geographic area.
