参数调整是模拟复杂现象和用另一种模式替换一种集体模式的有用方法。然而，这种方法可能无法解释复杂系统中的代理如何选择适当的参数或灵活地响应多变的环境。在网络演化中也发现了类似的问题，其中特征网络结构的出现带来了问题。在以前的工作中，我在网络上开发了一个鹰鸽游戏，其中个别玩家有时会断开与他们的合作伙伴的链接，或者除了策略更新之外还连接到新的合作伙伴。在这个博弈中，参与者通过考虑局部层次结构来协调链路连接/断开规则;我发现，这个规则的协调在某个时间呈现出无标度网络的出现，但在另一个时间却不是这样。当鹰派球员灭绝时，枢纽节点可能会出现。在这项工作中，我研究了链接的演变和集线器节点，将链接到网络结构的演变之间的关系，并发现网络结构可以根据竞争的进展，链路连接/断开不同的演变。
Parameter tuning is a useful method for modelling complex phenomena and replacing one collective pattern with another pattern. However, this approach may not explain how agents in a complex system select an adequate parameter or respond flexibly to a changeable environment. Similar problems are also found in the network evolution where the emergence of characteristic network structures poses a problem. In a previous work, I developed a hawk–dove game on the network where individual players sometimes disconnected links from their partners or connected a link to a new partner in addition to the strategy update. In this game, players coordinated the link connection/disconnection rule by considering the local hierarchy; I found that the coordination of this rule presented the emergence of a scale-free network at one time but not so at another time. Hub nodes may emerge when hawk players are extinct. In this work, I investigated the relationship between the link evolution and the evolution of hub nodes that will be linked to the network structure and found that the network structure could evolve differently according to the competitive progress of the link connection/disconnection.
