New soliton solutions like combined dark-bright, dark, periodic wave and singular soliton solutions are obtained. The equation is found to be a nonlinear self-adjoint, we construct the Cls using the new conservation theorem presented by Ibragimov. Physical interpretation for some of the obtained solutions are illustrated in Figures.eninfo:eu-repo/semantics/closedAccessKeMtcEjefNonlinear Self-AdjointnesslClsOptical SolitonArticle10.1016/j.cjph.2017.10.0102-s2.0-85037029214
