| 摘 要： | 著名的局域世界演化模型提出了局部演化的思想,但其局域世界的选取方式却不太符合现实世界的情况.由此提出了一个改进的局域世界演化模型,生成的网络同时具有无尺度和小世界特性,其度分布也同样表现为幂率和指数之间的某种过渡,而相对于原模型,却具有大得多的聚类系数,这符合真实世界的情况,使得本模型更有应用价值.

| Abstract: | The famous local-world model has presented a notion about local evolving,but the methodology it selected dose not conform to the reality very well.So,a modified version of the local-world evolving model is presented,with which the network generated possesses both the scale-free and small-world properties,and it's degree distribution represents a transition between power-law and exponential scaling.In contrast to the old model,it has a much bigger cluster coefficient which is in conformity with the real world,thus making the modified model more applicable than the old one. |

| Keywords: | local cluster evolving model scale-free small-world cluster coefficient |
