We investigate the number of maximal independent set queries required to reconstruct the edges of a hidden graph. We show that randomised adaptive algorithms need at least (² (n /) /) queries to reconstruct n-vertex graphs of maximum degree with success probability at least 1/2, and we further improve this lower bound to (² (n /) ) for randomised non-adaptive algorithms. We also prove that deterministic non-adaptive algorithms require at least (³ n /) queries. This improves bounds of Konrad, O'Sullivan, and Traistaru, and answers one of their questions. The proof of the lower bound for deterministic non-adaptive algorithms relies on a connection to cover-free families, for which we also improve known bounds.
