| Abstract | : | — In this work, we performed numerical simulation to investigate the effect of an “external field” to the evolution of public opinion in the Stauffer-Galam or two-dimensional Sznajd opinion model. Based on our results, the critical point d = dc depended on the probability p , where d and p are the initial density of spin up and the probability agents following the influence of the external field for such as a mass media. For typical value p =1 , the critical point occurred at 0.409 c d which causes the system reach a fixed point (complete consensus), i.e. all spin up or all spin down with the same probability. Moreover, we found a linear relation between the critical point dc and the probability p i.e., d p c with 0.09 . We also found a power law relation between the average relaxation time and the size of lattice L , i.e., L with 2.60. |
