Dynamic networks refer to a type of network structure that changes or evolves over time. This could include changes in the connections between nodes, changes in the strengths of connections, or changes in the attributes of nodes. Research in dynamic networks often involves studying how information or resources flow through the network, how the network adapts to changes in its environment, how patterns of connectivity emerge and change, and how the network structure affects its overall behavior. This research area is relevant in various fields such as social networks, transportation networks, biological networks, and communication networks. By studying dynamic networks, researchers can gain insights into complex systems and uncover new ways to optimize or control their behavior.
