HAT-Trie: A Cache-Conscious Trie-Based Data Structure For Strings
Tries are the fastest tree-based data structures for managing strings in-memory, but are space-intensive. The burst-trie is almost as fast but reduces space by collapsing trie-cha...

Optimal Cache-Oblivious Implicit Dictionaries
We consider the issues of implicitness and cache-obliviousness in the classical dictionary problem for n distinct keys over an unbounded and ordered universe. One finding in this ...
