Fig. 2.

Percentagewise convergence of the individual vdW-NB contributions with respect to the vdW-MB energy. Displayed cases include the binding energy of the DNA-ellipticine complex (blue circles) and the relative binding energies of a single base pair in A-DNA and B-DNA consisting of pure adenine-thymine (black triangles) and pure cytosine-guanine (red squares) sequences. The unfilled markers at N = 2 correspond to the predictions of the vdW-TB effective pairwise model for each of the aforementioned systems.
