Competition between two kinds of information among random-walking individuals

doi:10.1088/1674-1056/21/4/048902

Abstract A model is proposed to describe the competition between two kinds of information among N random-walking individuals in an L$\times$L square, starting from a half-and-half mixture of two kinds of information. Individuals remain or change their information according to their neighbors' information. When the moving speed of individuals v is zero, the two kinds of information typically coexist, and the ratio between them increases with L and decreases with N. In the dynamic case (v>0), only one information eventually remains, and the time required for one information being left scales as T_d～v^$\alpha$L^βN^$\gamma$.

Keywords: information spread random walk complex networks power law
