网络上的社交动态可能会加速或减速，这取决于网络中的哪些人对通信较早，哪些人对通信较晚。给定网络中的链路被顺序使用的顺序，我们称之为链路顺序，可能是网络上动态行为的强烈决定因素，潜在地为临时网络相对于静态网络的影响增加了新的维度。在这里，我们研究链接顺序对线性协调(即同步)动力学的影响。我们表明，协调速度在很大程度上取决于特定的链接顺序。此外，在转移到下一对个体之前，长时间应用每个单一链接以确保强大的成对协调通常不会增强整个网络的协调。我们还实现了一种简单的贪婪算法来优化链接顺序，从而有利于快速协调。
Social dynamics on a network may be accelerated or decelerated depending on which pairs of individuals in the network communicate early and which pairs do later. The order with which the links in a given network are sequentially used, which we call the link order, may be a strong determinant of dynamical behaviour on networks, potentially adding a new dimension to effects of temporal networks relative to static networks. Here we study the effect of the link order on linear coordination (i.e., synchronisation) dynamics. We show that the coordination speed considerably depends on specific orders of links. In addition, applying each single link for a long time to ensure strong pairwise coordination before moving to a next pair of individuals does not often enhance coordination of the entire network. We also implement a simple greedy algorithm to optimise the link order in favour of fast coordination.
