报告摘要：In intricate networks, the arrangement of connections, specifically the connectivity structure and coupling frameworks, significantly influences the behaviors of individual nodes, such as their synchronization state. Within this framework, time-varying networks have been recognized as more accurate models for investigating real-world phenomena. These time-varying structures typically adhere to predetermined time-variable rules. However, such pre-defined alterations may lack adaptiveness, potentially limiting the networks' flexibility. Conversely, introducing adaptivity to the time-variation rules can result in even more realistic networks. In real-world systems, the connections or interactions often undergo unpredictable changes over time. In essence, both time-varying and adaptive networks can be characterized as dynamic networks, continuously reconfiguring their structure based on predetermined rules. The dynamical states of the network's nodes influence these rules, particularly in adaptive networks. This adaptability mirrors the dynamic nature of real-world systems where unforeseen variations in connections or interactions occur, enhancing the authenticity of the network model. Within the synchronization domain, it has been unveiled that time-varying and adaptive networks possess the capacity to markedly influence network synchronization, often resulting in a considerable decrease in synchronization costs.
