Compressed Set Representations based on Set Difference

Published 30 Jan 2026 in cs.DS | (2601.23240v1)

Abstract: We introduce a compressed representation of sets of sets that exploits how much they differ from each other. Our representation supports access, membership, predecessor and successor queries on the sets within logarithmic time. In addition, we give a new MST-based construction algorithm for the representation that outperforms standard ones.
