Learning Strong Substitutes Demand via Queries
Paul W. Goldberg, Edwin Lock, Francisco Marmolejo-Cossío
This paper addresses the computational challenges of learning strong substitutes demand when given access to a demand (or valuation) oracle. Strong substitutes demand generalises t…

The Bitcoin protocol prescribes certain behavior by the miners who are responsible for maintaining and extending the underlying blockchain; in particular, miners who successfully s…
Learning Convex Partitions and Computing Game-theoretic Equilibria from Best Response Queries
Paul W. Goldberg, Francisco J. Marmolejo-Cossío
Suppose that an -simplex is partitioned into convex regions having disjoint interiors and distinct labels, and we may learn the label of any point by querying it. The learni…
