复杂网络度分布特征研究

Degree Distribution of Complex Networks

考察了复杂网络的不同模型,研究了在节点度总数不变条件下产生无标度现象的可能性。通过对OW S(择优W S)模型的提出和仿真,肯定了择优机制对形成网络节点度渐近分布特征的作用,并进一步指出,网络演化中进出择优机制的差异可能对其度分布特征产生重要影响。

Different models of free-scale networks are investigated, and the emerging possibility of freescale phenomenon in the networks is analyzed under the condition that the degree sum of all nodes is constant. The study indicates the simulation on OWS （optimal WS） model agrees with the optimal mechanism shows free-scale phenomenon. The difference between in-and out-mechanisms can affect the degree distribution in the networks.
