Abstract This paper obtains highly dispersive perturbed bright 1-soliton solution with cubic–quintic–septic nonlinearity by the aid of semi-inverse variational principle. The relation between the parameters, for sustaining solitons, naturally emerge during the course of soliton solution derivation.
