BINARY TREES AND HEAPS IN JAVA
... We can do this in O(log n) time, using a binary heap, by following this algorithm: (1) Add the element on the bottom level of the heap. (2) Compare the added element with its parent; if they are in the correct order, stop. (3) If not, swap the element with its parent and return to the previous step. ...

Efficient implementation of lazy suffix trees
... To implement a suffix tree, we basically have to represent three different items: nodes, edges, and edge labels. To describe our representation, we define a total order ≺ on the children of a branching node: let uv and uw be two different nodes in ST(t) that are children of the same branching node u ...

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.
