Automatic differentiation of algorithms, Proc. 1st SIAM Workshop, Beckenridge/ CO (USA) 1991, 169-180 (1991).
Summary: [For the entire collection see Zbl 0747.00030.]
The method of adjoint equations, or backward differentiation, seems to be particularly appropriate for solving a number of optimization and sensitivity problems that arise in the general context of numerical modeling of the atmospheric (and also oceanic) circulation. One such problem is assimilation of observations, which is discussed in some detail. A number of rules that have been defined for the practical coding of adjoint models are presented. The problems raised by the development and maintenance of adjoint codes are discussed.
