Dynamic perfect hash tables and cuckoo hash tables are two different data structures that support worst-case O(1) lookups and expected O(1)-time insertions and deletions. Both require O(n) auxiliary space and access to families of hash functions for their operations.
I think that both of these data structures are beautiful and brilliant in their own right, but I'm not sure I see how and when one of these would be preferable over the other.
Are there specific contexts in which one of these data structures has a clear advantage over the other? Or are they mostly interchangeable?
