Historical Queries Along Multiple Lines of Time Evolution
... The Vertical Query is an extension of the single-line historical queries to the case of multiple lines of evolution. The state of the evolving system and the notion of a state change can be defined in various ways, depending on the application. In the example above, the state is defined as a collect ...

... • If the tree is nonempty, the root must have at least one key. • Every node can contain at most 2t − 1 keys. Therefore, an internal node can have at most 2t children. • We say that a node is full if it contains exactly 2t − 1 keys. Jaruloj Chongstitvatana Chapter 2: Advanced Data Structures ...

Quadtree
A quadtree is a tree data structure in which each internal node has exactly four children. Quadtrees are most often used to partition a two-dimensional space by recursively subdividing it into four quadrants or regions. The regions may be square or rectangular, or may have arbitrary shapes. This data structure was named a quadtree by Raphael Finkel and J.L. Bentley in 1974. A similar partitioning is also known as a Q-tree. All forms of quadtrees share some common features: They decompose space into adaptable cells Each cell (or bucket) has a maximum capacity. When maximum capacity is reached, the bucket splits The tree directory follows the spatial decomposition of the quadtree.
