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?
Dynamic perfect hashing in the sense of Dietzfelbinger et al. only needs 2-independent hashing. While there are some results on simple hashing for cuckoo hash tables, such as twisted tabulation hashing and "Explicit and Efficient Hash Families Suffice for Cuckoo Hashing with a Stash", the original dynamic perfect hashing is more robust in some sense.

Hash Tables. (Hint: Diagrams might be helpful for parts a) and b). ) When inserting into hash table we insert at an index calculated by the key modulo the array size, what would happen if we instead did key mod (array_size*2), or key mod (array_size/2)? (Describe both cases). Theory answer Here Change your hashtable from the labs/assignments to be an array of linkedlists – so now insertion is done into a linkedlist at that index. Implement insertion and search. This...
