STEM2: A Fast and Space-efficient Data Structure for Exact Multi-Set Membership Query
A fast and space-efficient data structure that achieves 100% query accuracy and can support dynamic key updates for multi-set membership queries, and a minimized hashing scheme that requires only two hash computations per key lookup, significantly reducing computational overhead.
