我们对一类网络的拓扑结构进行了分析，这些网络在任意两个节点之间的路由尽可能短，同时保持网络中的拥塞尽可能低的要求方面是最优的。引人注目的是，我们发现了各种不同的拓扑结构，以及它们之间随着每个节点链路数量的变化而发生的新相变。我们的研究结果表明，在自然界中观察到的拓扑结构的出现可能源于生长机制和动力机制与选择过程的相互作用。
We present an analysis of the topologies of a class of networks which are optimal in terms of the requirements of having as short a route as possible between any two nodes while yet keeping the congestion in the network as low as possible. Strikingly, we find a variety of distinct topologies and novel phase transitions between them on varying the number of links per node. Our results suggest that the emergence of the topologies observed in nature may arise both from growth mechanisms and the interplay of dynamical mechanisms with a selection process.
