Fusion tree

Fusion tree

A fusion tree is a tree data structure that implements an associative array with integer keys up to a fixed size; by exploiting the constant-time machine word multiplication operation available on many real processors, it is able to achieve all operations in

:Oleft(frac{log n}{log log n} ight)

time ("see Big O notation"), which is slightly faster asymptotically than a self-balancing binary search tree.
