Bounds for Weight Balanced Trees
نویسنده
چکیده
It has been shown that the cost W of a weight balanced binary tree satisfies the inequalities, H 5 W 5 H + 3, where H is the entropy of the set of the leaves. For a class of “smooth” distributions the inequalities, H 5 W 5 H + 2, are derived. These results imply that for sets with large entropy the search times provided by such trees cannot be substantially shortened when binary decisions are being used.

General Balanced Trees
We show that, in order to achieve efficient maintenance of a balanced binary search tree, no shape restriction other than a logarithmic height is required. The obtained class of trees, general balanced trees, may be maintained at a logarithmic amortized cost with no balance information stored in the nodes. Thus, in the case when amortized bounds are sufficient, there is no need for sophisticate...
متن کاملA Framework for Index Bulk Loading and Dynamization
Abst rac t . In this paper we investigate automated methods for externalizing internal memory data structures. We consider a class of balanced trees that we call weight-balanced partitioning trees (or wp-trees) for indexing a set of points in Rd. Well-known examples of wp-trees include fed-trees, BBD-trees, pseudo quad trees, and BAR trees. These trees are defined with fixed degree and are thus...
متن کاملOn the Average Height of b-Balanced Ordered Trees
An ordered tree with height h is b-balanced if all its leaves have a level l with h − b <= l <= h, where at least one leaf has a level equal to h − b. For large n, we shall compute asymptotic equivalents to the number of all b-balanced ordered trees with n nodes and of all such trees with height h. Furthermore, assuming that all b-balanced ordered trees with n nodes are equally likely, we shall...
