- balanced tree — (algorithm) 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.

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).
