A single bright highly dispersive optical soliton solution is recovered from semi-inverse variational principle. The model contains six power law nonlinear terms that constitute self-phase modulation effect which was proposed by Kudryashov. The amplitude-width relation of the soliton was finally recovered by Cardano's approach with appropriate and necessary constraints that are presented.
