Reconstructs bidder preferences and the allocator from only which bidders show up and who wins, with two concrete models and provable mistake bounds. For single-item pairwise arrivals the problem matches n log n lower/upper limits; for combinatorial single-minded bidders it learns the conflict graph and priority order with n^2 mistakes (optimal) via an online decision-list style update and edge deletions. Unit-demand with observed allocations reduces to an nm universe giving ~n m log m bounds or a faster hybrid using ellipsoid/separation oracle updates. For stochastic bids the Kaplan–Meier estimator recovers distributions above the observable threshold by setting reserve prices and using participatory samples.
