摘要：
This paper studies the Biswas-Milovic equation, which is a generalized version of the nonlinear Schrodinger equation, with dual-power law nonlinearity. The G'/G-expansion method is employed to extract the dark 1-soliton solution from the equation. The results have a similar setting to the ones obtained earlier by the ansatz approach. Both constant and time-dependent coefficients are taken into consideration.
