predictability
Predictability refers to the degree to which a correct quantitative or qualitative prediction can be made about the condition of a system. While the second law of thermodynamics allows statements about a desired state of equilibrium and the steady state of some dissipative systems can be predicted, there is no general rule for predicting the time development of a system that is far from equilibrium . This is especially true for chaotic systems , the predictability of which usually decreases exponentially over time.
To quantify the predictability, the divergence of the system trajectories in the phase space can be used as they are u. a. is measured by Lyapunov exponent .
