Robust optimization formulation
WebWe investigate an optimization problem governed by an elliptic partial differential equation with uncertain parameters. We introduce a robust optimization framework that accounts for uncertain model parameters. The resulting nonlinear optimization problem has a bilevel structure due to the min-max formulation. To approximate the worst case in ... WebJan 1, 2024 · Tractable robust models requires a convex optimization formulation which is are often handled by dualization ( Bertsimas and de Ruiter, 2016 ), reformulation of the robust counterpart (e.g., See and Sim, 2010, Guillaume et al., 2024 ), Lagrangian duality ( Rodrigues et al., 2024 ), dynamic programs (e.g., Bienstock and Özbay, 2008, Agra et al., …
