摘要
A weighted Olami, Feder, and Christensen (OFC) model, improving the redistribution rule of the original model, has been introduced. It can be seen as a generalization of the OFC model and exhibits Self-organized criticality (SOC) behavior, too. The stress evolution process has been accelerated and the nontrivial relationship between the exponent of 1/f and the control parameter has been reported. Although our model is simple, we obtained more reasonable avalanche dimensions than with the previous model.
