AA trees are named for Arne Andersson, their inventor.AA trees are a variation of the red-black tree, a form of binary search tree which supports efficient addition and deletion of entries. Unlike red-black trees, red nodes on an AA tree can only be added as a right subchild. In other words, no red node can be a left sub-child. This results in the simulation of a 2-3 tree instead of a 2-3-4 tree, which greatly simplifies the maintenance operations. The maintenance algorithms for a red-black tree need to consider seven different shapes to properly balance the tree:File:Red Black Shape Cases.svgAn AA tree on the other hand only needs to consider two shapes due to the strict requirement that only right links can be red:File:AA Tree Shape Cases.svg"@en }
