TL;DR

The online assignment with forecast problem is formulated, a version of the online allocation problem where the algorithm has access to random samples from the future set of arriving vertices, and it is proved that representing the primal solution using such a compact allocation plan yields a robust online algorithm which makes near-optimal online decisions.

Abstract

Motivated by the allocation problem facing publishers in display advertising we formulate the online assignment with forecast problem, a version of the online allocation problem where the algorithm has access to random samples from the future set of arriving vertices. We provide a solution that allows us to serve Internet users in an online manner that is provably nearly optimal. Our technique applies to the forecast version of a large class of online assignment problems, such as online bipartite matching, allocation, and budgeted bidders, in which we wish to minimize the value of some convex objective function subject to a set of linear supply and demand constraints.
