A Nearly Instance-optimal Differentially Private Mechanism for Conjunctive Queries

Summary: DP mechanism for conjunctive/graph-pattern counts achieving near-instance-optimal error (constant-factor relaxation of instance-optimality). Constructive algorithm with provable per-instance near-optimal error, replacing prior approaches lacking any optimality guarantees. (summarized by gpt-5-mini on Feb 09 2026)
