The classic area of online algorithms requires us to make decisions over time as the input is slowly revealed, without (complete) knowledge of the future. This has been widely studied, e.g., in the competitive analysis model ­­­and, in parallel, in the model of regret minimization. Another widely studied setting incorporates stochastic uncertainty about the input; this uncertainty reduces over time, but postponing decisions is either costly or impossible. Problems of interest include stochastic optimization, stochastic scheduling and queueing problems, bandit problems in learning, dynamic auctions in mechanism design, secretary problems, and prophet inequalities. Recent developments have shown connections between these models, with new algorithms that interpolate between these settings and combine different techniques. The goal of the workshop is to bring together researchers working on these topics, from areas such as online algorithms, machine learning, queueing theory, mechanism design, and operations research, to exchange ideas and techniques and forge deeper connections.
