... (but not both). In the case of edge insertions (resp. deletions), the partially dynamic algorithm or problem is called incremental (resp. decremental). The main goal of a dynamic algorithm is to use structural properties of the current graph G in order to handle updates efficiently, i.e., without reso ...

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.
