0 Rank - Balanced Trees

Since the invention of AVL trees in 1962, many kinds of binary search trees have been proposed. Notable are red-black trees, in which bottom-up rebalancing after an insertion or deletion takes O(1) amortized time and O(1) rotations worst-case. But the design space of balanced trees has not been fully explored. We continue the exploration. Our contributions are three. We systematically study the...

Amortized Rotation Cost in AVL Trees

An AVL tree [1] is the original type of balanced binary search tree. An insertion in an n-node AVL tree takes at most two rotations, but a deletion in an n-node AVL tree can take Θ(log n). A natural question is whether deletions can take many rotations not only in the worst case but in the amortized case as well. A sequence of n successive deletions in an n-node tree takes O(n) rotations [3], b...

University of Alberta Asymmetry in Binary Search

In this paper we explore the relationship between asymmetries in deletion algorithms used in updating binary search trees, and the resulting long term behavior of the search trees. We show that even what would appear to be negligible asymmetric eeects accumulate to cause long term degeneration. This persists even in the face of other eeects that would appear to counteract the long term eeects. ...

Probabilistic analysis of the asymmetric digital search trees

In this paper, by applying three functional operators the previous results on the (Poisson) variance of the external profile in digital search trees will be improved. We study the profile built over $n$ binary strings generated by a memoryless source with unequal probabilities of symbols and use a combinatorial approach for studying the Poissonized variance, since the probability distribution o...
