Questions tagged [chaos]

Anything related to chaotic systems or chaos theory. Chaotic systems are systems that are extremely sensitive to initial conditions (e.g. round-off error in data stored digitally) thus leading to the impossibility of predicting their long-term evolution. The tag is mostly relevant to cases where algorithms show chaotic behavior.

Lyapunov Exponent estimation in Java / pseudocode

I'd like to estimate the predictability of a time series that is possibly chaotic. For this reason I thought that the Lyapunov exponents would be a good candidate. I've done some research on the Internet but the explanations that I've found are not…
