“…For most real-life nonlinear problems, it is not always possible and sometimes not even advantageous to express exact solutions of nonlinear differential equations explicitly in terms of elementary functions or independent spatial and/or temporal variables; however, it is possible to find approximate solutions. In recent years, many ingenious analytical methods have been developed for solving different kinds of strongly nonlinear equations, such as homotopy perturbation method [7,8], energy balance method [9][10][11][12], variational iteration method [13,14], variational approach [15][16][17][18], iteration perturbation method [19], Hamiltonian Approach [20], max-min approach [21][22][23][24], parameter expansion method [25], and other analytical and numerical methods [26][27][28][29][30].…”
