How to measure Chaos?

  1. Feb 28, 2012 #1
    Is there any parameter that represents the chaotic-ness of a system?

    For example, can we show that a 4-body system is in general more chaotic than a 3-body problem?

    Thank you : )

    I believe there are a few possible measures,
    The Lyapunov exponent would be one example.

    Lyaponuv exponent is the basic one; it indicates the rate of divergence of two closely spaced sets of initial conditions.
