       abstract = "Classical methods of constrained optimization are often based on the assumptions
         that projection onto the constraint manifold is routine, but accessing second-derivative information
         is not. Both assumptions need revision for the application of optimization to systems constrained by
         partial differential equations, in the contemporary limit of millions of state variables and in the
         parallel setting. Large-scale PDE solvers are complex pieces of software that exploit detailed
         knowledge of architecture and application and cannot easily be modified to fit the interface
         requirements of a blackbox optimizer. Furthermore, in view of the expense of PDE analyses,
         optimization methods not using second derivatives may require too many iterations to be practical.
         For general problems, automatic differentiation is likely to be the most convenient means of
         exploiting second derivatives. We delineate a role for automatic differentiation in matrix-free
         optimization formulations involving Newton's method, in which little more storage is required
         than that for the analysis code alone.",
