XTree is a file manager program originally designed for use under DOS. It was published by Executive Systems, Inc. (ESI) and first released on 1 April 1985, and became highly popular. [1] . The program uses a character-mode interface, which has many elements typically associated with a graphical user interface.

In computer science tree data structures, an X-tree (for eXtended node tree[1]) is an index tree structure based on the R-tree used for storing data in many dimensions.

The present project indexes 170,653 spotify songs within an X-tree and allows querying the k-nearest neighbors for a given point. The original file can be found in the following website.

proved index structure for high-dimensional data, the X-tree (cf. section 3). The main idea of the X-tree is to avoid over- lap of bounding boxes in the directory by using a new orga- nization of the directory which is optimized for high- dimensional space. The X-tree avoids splits which would re-

The X‑tree (eXtended node tree) is a spatial access method that supports efficient query processing for high‐dimensional data. It supports not only point data but also extended spatial data.

In this chapter we present the PK-tree which is an index structure for high dimensional point data. The proposed indexing structure can be viewed as combining aspects of the PR-quad or K-D tree but where unnecessary nodes are eliminated.

An X-tree is a mathematical tree structure whose leaves are assigned labels from a set X. X -trees can be viewed as one of the foundational concepts of mathematical phylogenetics, as evolutionary trees of organisms consider the relationships among taxonomic groups whose names correspond to the labels in set X .

The X-tree (eXtended node tree) [1] is a spatial access method [2] that supports efficient query processing for high-dimensional data. It supports not only point data but also extended spatial data. The X-tree provides overlap-free split whenever it is possible without allowing the tree to degenerate; otherwise, the X-tree uses

Oct 28, 2023 · ZTreeWin is an extremely fast and flexible text-mode file/directory manager for all versions of Windows (both 32-bit and 64-bit), modeled closely on the legendary XTreeGold(tm).

In this paper, we propose a new method for indexing large amounts of point and spatial data in high-dimensional space. An analysis shows that index structures such as the R*-tree are not adequate for indexing high-dimensional data sets. The major problem of R-tree-based index structures is the overlap of the bounding boxes in the ...
