Query: Variable separated ODE method--A powerful tool for testing traveling
  wave solutions of nonlinear equations   The variable separated ODE method is extended by choosing the additional
variable separated equation as the general elliptic equation. More exact
traveling wave solutions of nonlinear equations are obtained by using the
method of comparison of coefficients and the known solutions of the auxiliary
equation.
