Robust Convex Optimization | Mathematics of Operations ...

1998-11-1 · Abstract. We study convex optimization problems for which the data is not specified exactly and it is only known to belong to a given uncertainty set U, yet the constraints must hold for all possible values of the data from U. The ensuing optimization problem is called robust optimization. In this paper we lay the foundation of robust convex ...
