where α i , β i and µ are parameters. While the µ is typically set to 0.33, the α i and β i can be adjusted. Note that subscript i is introduced here to represent the "adaptive" aspect of current proposals. Normally, the subscript i is unnecessary, as the same α and β are utilized for both SCF (i=1) and response parts (i=2) of computations. In the case of CAMh-B3LYP, the α 1 and β 1 are 0.19 and 0.31, respectively and the corresponding values for α 2 and β 2 are identical.(See Table ) According to the previous statistical analysis, the combination of CAMh-B3LYP (α 1 =0. 19, (see Table and Fig. ), where DT stands for "Doubly Tuned".
