       abstract = "We compare the Tangent-on-Tangent and the Tangent-on-Reverse strategies to build
         programs that compute second derivatives (a Hessian matrix) using automatic differentiation. In the
         specific case of a constrained functional, we find that Tangent-on-Reverse outperforms
         Tangent-on-Tangent only above a relatively high number of input parameters. We describe the
         algorithms to help the end-user apply the two strategies to a given application source. We discuss
         the modification needed inside the automatic differentiation tool to improve Tangent-on-Reverse
         differentiation.",
