Professor Bray's talk is titled "Logarithmic Regret in Multisecretary and Online Linear Programming Problems with Continuous Valuations." In this talk, he studies a general revenue management problem in which n customers arrive sequentially over n periods, and you must dynamically decide which to satisfy. He studies this system's regret, which is the additional utility you could get if you didn't have to make decisions on the fly. He provides a new proof that this regret is bounded in n when valuations are drawn from a discrete distribution, and shows that this regret grows like log(n) when valuations are drawn from a continuous distribution.

Robert Bray is an associate professor of operations management at Northwestern University.
