چکیده
Exact solutions are important in many branches of engineering and physics because of inhomogeneity, nonlinearities and some general boundary conditions. Hence, applied mathematicians, engineers and physicists are forced to find approximate solutions of the problems in these areas. So, there are many different methods such as sine-cosine method, tanh-coth method, exp-function method, G’/G-expansion method etc. which based on complementary equations, to obtain the exact solutions of nonlinear partial differential equations. The important thing is to find original expansion. The aim of this work is to determine the ansatz which gives less computation. Key-Words: / G G -expansion method, auxiliary equation method, ansatz

Solitons are ubiquitous and exist in almost every area from sky to bottom. For solitons to appear, the relevant equation of motion must be nonlinear. In the present study, we deal with the Korteweg-deVries (KdV), Modied Korteweg-de Vries (mKdV) and Regularised LongWave (RLW) equations using Homotopy Perturbation method (HPM). The algorithm makes use of the HPM to determine the initial expansion...
