Simulation

Definition

A simulation is a computational method used to model the behavior of complex systems by imitating their operations over time. This technique allows researchers to experiment with and analyze systems that may be difficult or impossible to observe directly, especially in the study of dynamic phenomena like chaos. By creating virtual environments, simulations can provide insights into the intricate interactions and feedback loops that characterize chaotic systems.
