“…Author of [5] found an approximate solution of a nonlinear equation with Riemann-Liouville's fractional derivatives by He's variational iterational method. Several methods have been used to solve fractional partial differential equations, such as Adomian's decomposition method (ADM) [6,7], Fourier transform method [8], Laplace transform method [2,3,9], and so on.
