Searching for multi-soliton solution to generalized Caudrey-Dodd-Gibbon-Kaeada equation with homogeneous balance method

The homogeneous balance method is used to obtain the Hirota transformation which transforms the equation into the Hirota bilinear form,and the relation between these two methods is explained.The results show that there exists a general method which transforms some soliton equations into Hirota bilinear forms.
