Comment on “Variational iteration method for fractional calculus using He’s polynomials”. (English) Zbl 1256.65091

Summary: Recently, Y. Liu [ibid. 2012, Article ID 727031, 10 p. (2012; Zbl 1246.65191)] applied the variational homotopy perturbation method for fractional initial boundary value problems. This note concludes that the method is a modified variational iteration method using He’s polynomials. A standard variational iteration algorithm for fractional differential equations is suggested.
