Distributionally Robust Optimization over Wasserstein Balls with i.i.d. Structure

Andrey Kharitenko, Marta Fochesato, Anastasios Tsiamis +2

We consider distributionally robust optimization problems where the uncertainty is modeled via a structured Wasserstein ambiguity set. Specifically, the ambiguity is restricted to…

Semismooth Newton Methods for Risk-Averse Markov Decision Processes

Matilde Gargiani, Francesco Micheli, Anastasios Tsiamis +1

Inspired by semismooth Newton methods, we propose a general framework for designing solution methods with convergence guarantees for risk-averse Markov decision processes. Our appr…

Operator Splitting for Convex Constrained Markov Decision Processes

Panagiotis D. Grontas, Anastasios Tsiamis, John Lygeros

We consider finite Markov decision processes (MDPs) with convex constraints and known dynamics. In principle, this problem is amenable to off-the-shelf convex optimization solvers,…
