Abstract

We present an algorithm for hashing $\lfloor \alpha n \rfloor$ elements into a table with n separate chains that requires O(1) deterministic worst-case insert time and O(1) expected worst-case search time for constant $\alpha$. We exploit the connection between two-way chaining and random graph theory in our techniques.
