| 摘 要： | 在某些实际问题中,网络中节点的权重具有方向性。因此,在BBV模型和点权有限加权网络模型(LBBV)的基础上,提出了一个基于点权有限的有向加权网络模型。该模型着重考虑了加权网络节点强度的有限性和节点权重的有向性,使之具有更广泛的实际背景和应用范围。通过理论分析,当Si>2mw0,So>2mw0时,网络可以一直演化下去,并且该模型节点的出入度分布及节点的出入强度分布均服从幂律指数为2～3的幂律分布。仿真结果验证了理论分析的正确性。

| Abstract: | For some practical applications,there exist some networks with directional weights at nodes.Based on the BBV model and the LBBV model,this paper presents a directed model for weighted networks based on limited node strength.The model mainly considers the limited node strength and directional weights at nodes,which make the improved model with a wide range of practical backgrounds and scope of application.According to the theoretical analysis,when the limited strength Si > 2mw0,So > 2mw0,the network will wor... |
