Fig. 1: A binary search tree of size 9 and depth 3, with 8 at the root. In computer science, a binary search tree (BST), also called an ordered or sorted binary tree, is a rooted binary tree data structure with the key of each internal node being greater than all the keys in the respective node's left subtree and less than the ones in its right subtree.
Binary, or half-interval, searches repeatedly target the center of the search structure and divide the search space in half. Comparison search algorithms improve on linear searching by successively eliminating records based on comparisons of the keys until the target record is found, and can be applied on data structures with a defined order.

The fastest portable approaches to simulate clz are a combination of binary search and table lookup: an 8-bit table lookup (2 8 =256 1-byte entries) can replace the bottom 3 branches in binary search. 64-bit operands require an additional branch. A larger width lookup can be used but the maximum practical table size is limited by the size of L1 ...
Uniform binary search is an optimization of the classic binary search algorithm invented by Donald Knuth and given in Knuth's The Art of Computer Programming.It uses a lookup table to update a single array index, rather than taking the midpoint of an upper and a lower bound on each iteration; therefore, it is optimized for architectures (such as Knuth's MIX) on which
In the first stage it performs an exponential search, also known as a galloping search, until finding a k such that R1[2 k−1 − 1] < x <= R1[2 k − 1], i.e. a region of uncertainty comprising 2 k−1 − 1 consecutive elements of R1. The second stage performs a straight binary search of this region to find the exact location in R1 for x ...
Cubesort's algorithm uses a specialized binary search on each axis to find the location to insert an element. When an axis grows too large it is split. When an axis grows too large it is split. Locality of reference is optimal as only four binary searches are performed on small arrays for each insertion.
