J. Utke and U. Naumann, "Combinatorial Problems in Open/AD," Preprint ANL/MCS-P1595-0309, March 2009. [pdf]

Computing derivatives using automatic differentiation methods entails a variety of combinatorial problems. The OpenAD tool implements automatic differentiation as source transformation of a program that represents a numerical model. We select three combinatorial problems and discuss the solutions implemented in OpenAD. Our intention is to explain the specific parts of the implementation so that readers can easily use OpenAD to investigate and develop their own solutions to these problems.
