A vector database, vector store or vector search engine is a database that can store vectors (fixed-length lists of numbers) along with other data items. Vector databases typically implement one or more Approximate Nearest Neighbor algorithms, [1] [2] [3] so that one can search the database with a query vector to retrieve the closest matching database records.

The term bristlecone pine covers three species of pine tree (family Pinaceae, genus Pinus, subsection Balfourianae). All three species are long-lived and highly resilient to harsh weather and bad soils. One of the three species, Pinus longaeva, is among the longest-lived life forms on Earth. The oldest of this species is more than 4,800 years ...
R-tree. R-trees are tree data structures used for spatial access methods, i.e., for indexing multi-dimensional information such as geographical coordinates, rectangles or polygons. The R-tree was proposed by Antonin Guttman in 1984 [2] and has found significant use in both theoretical and applied contexts. [3]
A pine is any conifer tree or shrub in the genus Pinus (/ ˈpaɪnəs /) [1] of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae. World Flora Online accepts 187 species names of pines as current, with additional synonyms, making it the largest family among the conifers. [2]

Methuselah is a 4,856-year-old [1] Great Basin bristlecone pine (Pinus longaeva) tree growing high in the White Mountains of Inyo County in eastern California. [2][3] It is recognized as the non- clonal tree with the greatest confirmed age in the world. [4] Its old age is a result of harsh weather and a lack of nutrients, which slow down the ...
