ABSTRACT=In this article, (3+1)-dimensional generalized Shallow Water-like (gSWl) equation is discussed using Lie symmetry analysis method. The optimal system is obtained based on the adjoint table of the generators of the equation. Exact solutions of the equation are constructed by applying symmetry reduction, Exp(−φ(ξ)) expansion method, Exp-function expansion method, Riccati equation method, and (G'/G) expansion method. The physical structures of dark soliton, kink wave, and periodic solutions are derived via numerical simulations.
