Computer simulations

Definition

Computer simulations are digital models that replicate real-world processes or systems, enabling the analysis of complex behaviors and predictions of future outcomes. They play a crucial role in chaos theory by allowing researchers to visualize and understand dynamic systems like weather patterns or population dynamics, often revealing sensitive dependencies on initial conditions, which is fundamental to concepts like the Butterfly Effect.
