Augmenting Data Structures, Dynamic Order Statistics, Interval Trees
... Time = O(h) = O(lg n), since INTERVAL-SEARCH does constant work at each level as it follows a simple path down the tree. List all overlapping intervals: • Search, list, delete, repeat. • Insert them all again at the end. Time = O(k lg n), where k is the total number of overlapping intervals. This is ...

An Improved Reconstruction Method for Porous Media Based on Multiple-point Geostatistics
... assumption of isotropy in orthogonal directions. At every voxel (volume pixel) in order to assign pore space or grain state, three principal orthogonal planes XY, XZ, and YZ intersecting this voxel are used to find conditional data on these planes. But the main limitation of this method is that the ...

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.
