A computational model is a mathematical model or simulation that is created to study and predict the behavior of complex systems using computers. These models can simulate various processes, such as physical phenomena, biological systems, social behavior, and economic trends, by representing them in a digital format. Computational models are used in various fields, including physics, biology, engineering, and social sciences, to better understand and analyze the underlying mechanisms of these systems. Researchers use computational models to test hypotheses, explore different scenarios, and make predictions about how systems may behave under different conditions. By simulating complex systems on computers, researchers can gain insights that may not be possible to obtain through experimentation or observation alone.
