Table 3. Interaction energies (eV) of small organic molecules and gold clusters, computed with different DFT methods. The mean error (ME), mean absolute error (MAE) and mean absolute relative error (MARE) of each method with respect to CCSD (T) are reported in the last lines. For each row the result in best agreement with CCSD (T) calculations is highlighted in bold style, the one in worst agreement is underlined. hPBEint
