通过节点游走归并复杂网络

Subsuming Complex Networks by Node Walks

Alexandre Benatti, Luciano da F. Costa

AI总结:

本文提出用节点游走动力学归并复杂网络,在三种网络和三种游走规则下发现归并过程强烈依赖网络拓扑与游走准则,并揭示了初始度与累积强度的相关性及不同组合下的强度特征。

摘要:

本文研究了图与复杂网络中节点游走的概念,即一个或多个节点移动到相邻节点,并在此过程中纳入相应的连接。随后将这类动力学应用于归并复杂网络。考虑了三种类型的网络(Erdős–Rényi、Barabási–Albert以及一种几何模型),同时考察了三种节点游走启发式规则(均匀随机、最大度、最小度)。得到并描述了若干有趣的结果,其中包括发现归并动力学强烈依赖于网络的具体拓扑结构以及控制节点游走的准则。这一结果促使将节点游走作为研究网络拓扑与动力学之间关系的模型。此外,对于某些网络类型与动态规则的组合,观察到初始节点度与游走节点累积强度之间存在较高的相关性,从而可以根据游走节点周围的初始拓扑粗略预测归并的某些性质;但研究发现,这并不足以完全确定归并动力学。另一个有趣的结果涉及在所考虑的几种网络类型与归并规则组合下,游走节点强度沿迭代过程呈现出相当不同的特征。

英文摘要:

The concept of node walk in graphs and complex networks has been addressed, consisting of one or more nodes that move into adjacent nodes, henceforth incorporating the respective connections. This type of dynamics is then applied to subsume complex networks. Three types of networks (Erdós- Rény, Barabási-Albert, as well as a geometric model) are considered, while three node walks heuristics (uniformly random, largest degree, and smallest degree) are taken into account. Several interesting results are obtained and described, including the identification that the subsuming dynamics depend strongly on both the specific topology of the networks as well as the criteria controlling the node walks. The use of node walks as a model for studying the relationship between network topology and dynamics is motivated by this result. In addition, relatively high correlations between the initial node degree and the accumulated strength of the walking node were observed for some combinations of network types and dynamic rules, allowing some of the properties of the subsumption to be roughly predicted from the initial topology around the waking node which has been found, however, not to be enough for full determination of the subsumption dynamics. Another interesting result regards the quite distinct signatures (along the iterations) of walking node strengths obtained for the several considered combinations of network type and subsumption rules.
