我们引入网络效率的概念来衡量网络交换信息的效率。通过使用这种简单的方法，小世界网络被视为具有全局和局部效率的系统。这为“小世界”的概念提供了明确的物理意义，也为加权和未加权网络提供了精确的定量分析。我们研究神经网络和人造通信和运输系统，并表明它们构建的基本一般原则实际上是高效率的小世界原则。
We introduce the concept of efficiency of a network as a measure of how efficiently it exchanges information. By using this simple measure, small-world networks are seen as systems that are both globally and locally efficient. This gives a clear physical meaning to the concept of "small world," and also a precise quantitative analysis of both weighted and unweighted networks. We study neural networks and man-made communication and transportation systems and we show that the underlying general principle of their construction is in fact a small-world principle of high efficiency.
