Npunt
Npunt is a fictional construct used in computer science pedagogy to illustrate the concept of a multidimensional data point that carries additional metadata. The term is not a formal standard but appears in textbooks and online tutorials as a generic placeholder for a point in N-dimensional space used in discussions of indexing and similarity search.
Definition and structure: An Npunt consists of a coordinate vector (x1, x2, ..., xN), a unique identifier,
Operations: Common operations include distance calculation between two Npunts under a chosen metric (for example Euclidean
Applications: The concept is used to demonstrate data structures for high-dimensional data, such as k-d trees
History and status: Npunt lacks a formal specification; its usage varies by author. It functions as a
