Hamiltonian perturbation of optical solitons with parabolic law nonlinearity using three integration methodologies

This work secures optical soliton solution to the nonlinear Schrodinger's equation that appears with parabolic law nonlinearity and a couple of Hamiltonian type perturbation terms that are strong. Three integration schemes retrieve soliton solutions to the model. They are csch-function method, tanh-coth algorithm and modified simple equation technique.
