Making Abstract Domains Condensing
... program for a fixed query with a given initial description. On the other hand, a
goal-independent analyzer computes information on a program P for all the possible
initial queries for P , and then this whole abstract semantics allows to derive the
information of the analysis for a particular query. ...
... DEFINITION 3.1: An abstraction principle AE is satisfiable if and only if there is a cardinal κ such
that AE is κ-satisfiable. AE is unsatisfiable otherwise. SAT = the set of satisfiable abstraction
DEFINITION 3.2: An abstraction principle AE is Field conservative iff, for any theory T a ...

... model. We deal with this problem by retaining important
control variables in the abstract model. By this method we
avoid having to introduce an unreasonable number of predicates to simulate the behavior of the control variables. We
also show how to improve predicate abstraction by extracting useful ...

Abstraction in its main sense is a conceptual process by which general rules and concepts are derived from the usage and classification of specific examples, literal (""real"" or ""concrete"") signifiers, first principles, or other methods. ""An abstraction"" is the product of this process—a concept that acts as a super-categorical noun for all subordinate concepts, and connects any related concepts as a group, field, or category.Conceptual abstractions may be formed by filtering the information content of a concept or an observable phenomenon, selecting only the aspects which are relevant for a particular purpose. For example, abstracting a leather soccer ball to the more general idea of a ball selects only the information on general ball attributes and behavior, eliminating the other characteristics of that particular ball. In a type–token distinction, a type (e.g., a 'ball') is more abstract than its tokens (e.g., 'that leather soccer ball').Abstraction in its secondary use is a material process, discussed in the themes below.
