Some Novel Complex Dynamic Behaviors of a Class of Four-Dimensional Chaotic or Hyperchaotic Systems Based on a Meshless Collocation Method

Abstract EN

In the field of complex systems, there is a need for better methods of knowledge discovery due to their nonlinear dynamics.

The numerical simulation of chaotic or hyperchaotic system is mainly performed by the fourth-order Runge–Kutta method, and other methods are rarely reported in previous work.

A new method, which divides the entire intervals into N equal subintervals based on a meshless collocation method, has been constructed in this paper.

Some new complex dynamical behaviors are shown by using this new approach, and the results are in good agreement with those obtained by the fourth-order Runge–Kutta method.
