Robust Optimization — Methodology and Applications

WebFeb 4, 2024 · Robust linear programming addresses linear programming problems where the data is uncertain, and a solution which remains feasible despite that uncertainty is sought. The robust counterpart to an LP is not an LP in general, but is always convex. Webfor different classes of uncertainty sets. These robust counterparts are derived using the three steps that are described above. However, we need conic duality instead of LP duality in Step 2 to derive the tractable robust counterparts for the conic uncertainty set; see the fourth row of Table1. WebAug 8, 2003 · We extend the Robust Optimization methodology ([1, 3-6, 9, 13, 14]) to this situation by introducing the Adjustable Robust Counterpart (ARC) associated with an LP of the above structure. Often the ARC is significantly less conservative than the usual Robust Counterpart (RC), however, in most cases the ARC is computationally intractable (NP-hard). port forwarding service kubernetes
