CAS-Based Lock-Free Algorithm for Shared Deques
... For this algorithm, the ABA problem occurs only if a node is popped and then reinserted while a process holds a reference to it with the intent of using that reference as an expected value of an ABA-prone comparison. The simplest method for preventing the ABA problem is to include a tag with each po ...

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.
