Opinion evolution on the Sznajd model with family influence and age threshold

In this paper, the Sznajd model is used to study the opinion evolution but with parents influence and social influence division, as well as age barriers between different social members when interacting. To get the age information, we introduce Penna model to describe the human society. The result indicates that age does not affect the final consensus of the Sznajd model, but it has effect on the opinion distribution area when the initial state is 50% for either of the two opinions. With the presence of parents influence, the fluctuations of opinions in different age groups are different. When the site is not fully filled initially, with increasing age threshold, the fluctuation of opinions becomes larger.
