    • We calculated λ by simultaneously integrating two copies of Eqs. (123) with the same initial condition, and gave a small perturbation to one of the integrations. We used the same definition of the maximum Lyapunov exponent as (Formula presented)where (Formula presented)Here (Formula presented) is the perturbation given at (Formula presented) and (Formula presented) is the difference of the integration at (Formula presented) At (Formula presented) we rescale (Formula presented) to be very small and reset the simulation. We used (Formula presented)
