Z-order is calculated by bitwise interlacing of the keys. Insertion, deletion, and point query are done as with ordinary B+ trees. To perform range searches in multidimensional point data, however, an algorithm must be provided for calculating, from a point encountered in the data base, the next Z-value which is in the multidimensional search ...
The Z-ordering can be used to efficiently build a quadtree (2D) or octree (3D) for a set of points. [5] [6] The basic idea is to sort the input set according to Z-order.Once sorted, the points can either be stored in a binary search tree and used directly, which is called a linear quadtree, [7] or they can be used to build a pointer based quadtree.
Established scientists write kid-friendly articles on either core concepts or new discoveries in their fields. To make the scientific research comprehensible for the journal's late elementary and middle school audiences, the articles rely heavily on key words and glossary sections for scientific nomenclature.

This graph invariant was introduced by Haruo Hosoya in 1971. [1] It is often used in chemoinformatics for investigations of organic compounds. [2] [3]In his article, "The Topological Index Z Before and After 1971," on the history of the notion and the associated inside stories, Hosoya writes that he introduced the Z index to report a good correlation of the boiling points of alkane isomers and ...
