Improving Chaotic Features of Fractional Chaotic Maps

Two fractional chaotic maps, Lu and Chen have been analyzed using an innovative predictor-corrector method based on a non-uniform grid. An original law to control the grid size at each iteration has introduced. The choice of was shown play fundamental role obtain behavior for larger parameter range, while decreasing computational time. obtained results show that complexity resulting system in terms Lyapunov exponents, Fourier transforms chaos robustness is sensitive can be considerably improved by proposed method.
