From: Scaling in complex systems: a link between the dynamics of networks and growing interfaces
Log-log representation of the variance of the vertex degrees W as a function of time for the visibility graphs obtained from interfaces for the six growth processes studied.
The initial slope of the curves determines the scaling exponent b. One hundred visibility graphs, each one obtained from the corresponding interface at this time step, are analyzed. As it can be seen, a clear power law dependence appear for the six models. As it occurs with the critical exponent a, this exponent allows to discriminate between process that, according with the classical theory should have the same exponent.
