title = "Adjoint optimization",
abstract = "The adjoint method has a long history (Lions 1971) and is widely used in fluid control, airfoil optimization, meteorology, global helioseismology, and terrestrial seismology. Real-world optimization problems are typically functions of large numbers of parameters, ill posed, and computationally expensive. For instance, one may envisage the difficulty in minimizing drag due to flow over an airfoil or seeking a model of Earth{\textquoteright}s interior that optimally fits observed seismograms, simply due to large number of ways one may alter the system.",
