Table 3. Comparison of GGA-method and MDS-method in computation time.

Method	E1	E2	E3	E4	E5	E6	E7	E8	E9	E10
GGA-method	6.21	6.36	7.01	6.37	7.51	6.73	6.53	6.7	6.28	6.65
MDS-method	260.18	258.75	263.85	260.76	264.96	247.4	252.71	255.29	271.57	273.56

Note that the unit used for measuring computation time is second, E denotes experiment, for example, E1, means the first experiment.
