Abstract
Generating and using a high-speed, scalable, and easily updateable data structure are described. The proposed data structure provides minimal perfect hashing functionality while intrinsically supporting low-cost set-membership queries. In other words, in some embodiments, it provides at most one match candidate in a set of known arbitrary-length bit strings that is used to match the query.
