balanced tree : FOLDOC
balanced tree
An optimisation of a tree which aims to keep equal numbers of items on each {subtree} of each node so as to minimise the maximum path from the root to any {leaf node}. As items are inserted and deleted, the tree is restructured to keep the nodes balanced and the search paths uniform. Such an algorithm is appropriate where the overheads of the reorganisation on update are outweighed by the benefits of faster search.
A B-tree is a kind of balanced tree that can have more than two subtrees at each node (i.e. one that is not restricted to being a binary tree).
