Abstract
In this paper a class of robust two-stage combinatorial optimization problems with uncertain costs is discussed. It is assumed that the uncertainty is modeled by using a convex uncertainty set, for example of polyhedral or ellipsoidal shape. Several methods to compute exact and approximate solutions are introduced. Experimental results for robust two-stage version of the weighted set cover problem are presented.
