Advanced Topic 46 of 52 Data Structures
Van Emde Boas Trees
Structures supporting integer set operations in log-log time.
How it works
A vEB tree stores integers from a universe of size u recursively splitting into √u clusters, supporting insert, delete and successor in O(log log u).
Where it is used
Fast predecessor queries on small integer universes.
Common pitfall
Needs O(u) memory in the basic form.
Where it fits in the course
Van Emde Boas Trees is topic 46 of 52 in Data Structures, rated Advanced. It follows Fibonacci Heaps. The next topic is Cuckoo Hashing.
