Hyper-differential sensitivity analysis with respect to model discrepancy: Optimal solution updating
Joseph Hart, Bart van Bloemen Waanders
A common goal throughout science and engineering is to solve optimization problems constrained by computational models. However, in many cases a high-fidelity numerical emulation o…
