Extended elliptic function expansion solution to Modified Improved Boussinesq equation(II)

Sixteen families of Jacobian elliptic function double-periodic solutions of Modified Improved Boussinesq equation are found by using extended elliptic function expansion method.This method is further improved and then used for solving the Modified Improved Boussinesq equation.Eight families of new double-periodic solutions are obtained.The new method can be more effectively applied to other nonlinear differential equations.
