AB: Computational inverse methods require adjoint codes to evaluate products of the transposed Jacobian of the underlying numerical model with a direction in the image space. The reverse mode of automatic differentiation provides the theoretical basis for adjoint compilers to generate adjoint version of numerical simulation programs automatically. This technique has been used successfully in the context of a large number of applications from computational science and engineering as reported during the past four international workshops on the topic. The presentation gives an introduction to automatic differentiation and, in particular, its reverse mode in the context of ongoing research and tool development efforts (see http://www.autodiff.org).
