An intermediate level of approximation for computing the dual descriptor
Journal of Molecular Modeling, 2012 At present, there are two levels of approximation to compute the dual descriptor (DD). The first uses the total electronic density of the original system along with the electronic densities of the system with one more electron and one less electron, but this procedure is time consuming and normal termination of computation of total electronic densities
