Summary: In this letter, the Exp-function method with the aid of Maple is used to obtain generalized soliton solution and periodic solution with some free parameters for the symmetric regularized long wave (SRLW) equation. Suitable choice of parameters in the generalized solution leads to Darwish’s solution [A. A. Darwish
and A. Ramady
, Chaos Solitons Fractals 33, No. 4, 1263–1274 (2007; Zbl 1137.35420
)]. The result shows that Exp-function method is a powerful mathematical tool for solving nonlinear equations arising in mathematical physics.
