Profile and Height of Random Binary Search Trees
The purpose of this article is to survey recent results on distributional properties of random binary search trees. In particular we consider the profile and the height.
متن کاملCache-Oblivious B-Trees
We present dynamic search-tree data structures that perform well in the setting of a hierarchical memory (including various levels of cache, disk, etc.), but do not depend on the number of memory levels, the block sizes and number of blocks at each level, or the relative speeds of memory access. In particular, between any pair of levels in the memory hierarchy, where transfers between the level...

متن کاملThe Height of q-Binary Search Trees
The paper [8] introduces for the first time a meaningful q–model of binary search trees: instead of binary search trees, one considers tournament trees, which differ only marginally from binary search trees; if one starts from a permutation ( 1 2 ··· n π1 π2 ··· πn ) , then one inserts the number i instead of the number πi. Thus, traversing the tree in inorder, we might think of the associated ...
متن کاملOptimal Worst-Case Operations for Implicit Cache-Oblivious Search Trees
We close an open issue on dictionaries dating back to the sixthies. An array of n keys can be sorted so that searching takes O(log n) time. Alternatively, it can be organized as a heap so that inserting and deleting keys take O(log n) time. We show that these bounds can be simultaneously achieved in the worst case for searching and updating by suitably maintaining a permutation of the n keys in...
