Periodic solution to nonlinear oscillators without artificial noises by the homotopy perturbation method
This paper elucidates a wrong trend in solving nonlinear oscillators. The homotopy perturbation method leads to a period solution to a nonlinear oscillator with high nonlinearity, while the Parker–Sochacki method results in a chaotic one and it is invalid for solving nonlinear oscillators.
