techniques such as the Adomian method [12,16], perturbation
method, etc. showed it. The method gives rapidly convergent
successive approximations of the exact solution if such a solution
exists; otherwise a few approximations can be used for
numerical purposes. Another important advantage is that the
VIM method is capable of greatly reducing the size of calculation
while still maintaining high accuracy of the numerical
solution. Moreover, the power of the method gives it a wider
applicability in handling a huge number of analytical and
numerical applications. Many authors for different cases have
obtained some exact and numerical solutions of the generalized
Ito system (see [17–20]).
