A variational numerical method based on finite elements for the nonlinear solution characteristics of the periodically forced Chen system

Comparative performance of time spectral methods for solving hyperchaotic finance and cryptocurrency systems

“…Therefore, we rely on numerical methods for computation of solutions since the HCFS is actually a dynamical system that is described by a set of nonlinear ODEs. However most methods used to solve hyperchaotic systems based on finite difference methods [20,19], finite elements [16], homotopy analysis or perturbation methods (HAM/HPM) together with Adomian decomposition [7], etc. are known to suffer from the curse of dimensionality [1,18] and sometimes not capable of handling stiffness issues [9] that may arise in financial systems.…”
