Title: Decision rules for information discovery in multi-stage stochastic programmingSpeaker: Phebe VayanosAffiliation: Department of Computing - Imperial College LondonLocation: CPSE Seminar room (C615 Roderic Hill)Time: 5:00pmAbstract. Stochastic programming and robust optimization are disciplines concerned with optimal decision-making under uncertainty over time. Traditional models and solution algorithms have been tailored to problems where the order in... Read more »

Title: Scenario-Free Stochastic Programming with Polynomial Decision RulesSpeaker: Dimitra BampouAffiliation: Department of Computing - Imperial College LondonLocation: CPSE Seminar room (C615 Roderic Hill)Time: 5:00pmAbstract. Multi-stage stochastic programming provides a versatile framework for optimal decision making under uncertainty, but it gives rise to hard functional optimization problems since the adaptive recourse decisions must be modeled as...

Title: A Scenario Approach for Estimating the Suboptimality of Linear Decision Rules in Two-Stage Robust Optimization Speaker: Michael HadjiyiannisAffiliation: Department of Computing - Imperial College LondonLocation: CPSE Seminar room (C615 Roderic Hill)Time: 5:00pmAbstract. Robust dynamic optimization problems involving adaptive decisions are computationally intractable in general. Tractable upper bounding approximations can be obtained by requiring the... Read more »

Title: Robust Optimization of Dynamic Systems and Its Applications.Speaker: Dr. Boris Houska Affiliation: Location: CPSE Seminar room (C616 Roderic Hill)Time: 3:00pmAbstract. This talk gives an introduction to numerical methods for the robust optimization of uncertain dynamic systems. In contrast to standard differential equations, which describe the propagation of a single vector-valued trajectory in time, uncertain... Read more »
