Optimal Uncoordinated Unique IDs
Summary: Formalize the Uncoordinated Unique Identifiers Problem (UUIDP): n independent ID generators over universe [m] with an adversary issuing requests, no inter-instance communication, minimize cross-instance collision probability — first theoretical study. Provide and analyze algorithms: one worst-case optimal against oblivious adversaries, one within O(log) of optimal against adaptive adversaries, and one competitively optimal against both oblivious and adaptive adversaries.
