enclosureto

Enclosureto is a term used in theoretical discussions of containment relations to denote a directed enclosure relationship between two sets or regions within a common ambient space. The term is not widely standardized and appears in speculative, interdisciplinary, or modeling contexts rather than as a formal mathematical axiom.

Definition: In a given modeling framework, Enclosureto(A, B) holds when A is assigned to or lies within B, with B chosen as the enclosing region from a prescribed family of enclosures E. The relation emphasizes the direction from the interior element to its enclosing counterpart. Depending on the framework, B may be required to be minimal with respect to containment in E, or chosen according to additional constraints such as geometry, material, or spatial cost.

Computation and notation: Enclosureto is typically expressed as a binary predicate or function that maps a source A and a target B to true or false under the given rules. In some contexts, A may be a point or a set of points, and B a polygon, polyhedron, or other closed region.

Applications: The concept appears in design optimization, packaging, robotics, and geographic information systems to formalize containment decisions, allocate resources, or reason about visibility and access within enclosures.

History and usage: The term enclosureto is recent and informal. It is sometimes used as a flexible placeholder in discussions about containment modeling and is not part of a standard mathematical vocabulary.
