Dynamic changes refer to the study of how systems or phenomena evolve over time. This research area focuses on understanding the processes and mechanisms that drive changes in complex systems, such as ecosystems, social networks, or economic markets. Researchers in this field use a variety of mathematical and computational models to analyze dynamic changes and predict future trends. By studying the patterns and dynamics of different systems, researchers can gain insights into how they are affected by external factors and internal interactions. Overall, dynamic changes research aims to provide a deeper understanding of the behavior of complex systems and contribute to the development of more effective strategies for managing and responding to changes in the environment, society, and economy.
