Variational iteration method for solving a class of strongly nonlinear evolution equations. (Chinese. English summary) Zbl 1212.35065

Summary: A class of strongly nonlinear evolution equations is studied. Using the variational iteration method, the corresponding variational is first constructed, then the suitable initial approximation is selected; and then, by using the iteration method, the approximate solution of arbitrary degree of accuracy for the solitary wave is obtained.
