摘要:

文献中已经提出了几种无标度复杂网络的增长模型,最近一系列基于适应度的依恋模型越来越突出。然而,这种基于健康的依恋行为可能产生的过程还不太清楚,因此很难比较这些模型的相对优点。本文分析了一种进化机制,这将导致一个基于健康的依恋过程。特别是,它是证明了通过分析和数值方法,在同构网络中,最大暴露于节点不适合的最小化导致附件概率是成比例的节点健身。这一结果,然后扩展到异构网络,供应链网络被用作一个例子。

英文摘要:

Several growth models have been proposed in the literature for scale-free complex networks, with a range of fitness-based attachment models gaining prominence recently. However, the processes by which such fitness-based attachment behaviour can arise are less well understood, making it difficult to compare the relative merits of such models. This paper analyses an evolutionary mechanism that would give rise to a fitness-based attachment process. In particular, it is proven by analytical and numerical methods that in homogeneous networks, the minimisation of maximum exposure to node unfitness leads to attachment probabilities that are proportional to node fitness. This result is then extended to heterogeneous networks, with supply chain networks being used as an example.
