| Abstract: | BA model and randomlylinkedwithedge model which is equal to BA model are analyzed for scalefree networks.Based on the definition of edge's weight and node'KG-*4]s fitness,weightededge model and nodefitness model are presented.The equivalence of these models and BA model is proved by analytical computing,and the result of computer simulation also illustrates their equivalence.Comparison between the four equivalent models is presented. |
