Deterministic systems are main subject of chaos theory. Chaos theory holds a great concern about these deterministic systems. Especially those systems, this behavior can be predicted that is within the scope of principle, and related concepts. In the beginning, such chaotic systems tend to be predictable. Later on, they turn out to be random. It means that chaotic systems are predictable until a specific amount of time from their generation. This amount of time can be derived from three aspects:<br />- Level of expected uncertainty in the forecast or simply prediction<br />- Accuracy in the measurement of the current or last available stage<br />- Lyapunov time, which is the time scale fully dependant on system dynamics
