       abstract = "We present for the first time the tangent linear method applied to the algorithm
         for solving integral equations of the theory of simple liquids. The purpose of this method is to
         compute the exact derivatives of the pair-correlation function g(r) with respect to density and
         temperature, which appear in thermodynamic properties and in the self-consistent procedure. An
         automatic differentiation tool is applied to the numerical algorithm of the integral equation method
         that combines the Newton-Raphson and the traditional iterative techniques. It results in a tangent
         linear code for the integral equation proposed by Vompe and Martynov, which is applied to calculate
         the thermodynamic properties and the bridge functions of the Lennard-Jones fluid. The results
         suggest that the tangent linear method should be preferred over the different strategies of
         differentiation that have been used up to now. Moreover, a local formulation of the Gibbs-Duhem
         relation is tractable in this framework.",
