Both approximate solutions are compared with the numerical solutions for weakly and strongly nonlinear systems. For weakly nonlinear systems, both approximate solutions are in excellent agreement with numerical simulations. However, for strong nonlinearities, MS method is not give reliable results while MSLP method can provide acceptable solutions with numerical solutions. </span> </div>}, number={2}, publisher={Manisa Celal Bayar University}
