Solutions of Some Nonlinear Equations by a Direct Algebraic Method

In this paper, we present a direct algebraic method which is suggested by H. Zhang for the exact solutions of the Benjamin-Bona-Mahony (BBM), (3+1) dimensional Kadomtsev--Petviashvili (KP) and Caudrey-Dodd-Gibbon Kawada (CDGK) equation.
