In this paper, we construct new traveling wave solutions of some nonlinear evolution equations in mathematical physics via the (3+1)-dimensional potential-YTSF equation, the (3+1)-dimensional modified KdV-Zakharov-Kuznetsev equation, the (3+1)-dimensional Kadomtsev-Petviashvili equation and the (1+1)-dimensional KdV equation by using a generalized (G'/G)-expansion method, where G = G(xi) satisfies the Jacobi elliptic equation [G'(xi)](2) = P(G). Here, we assume that P(G) is a polynomial of fourth order. Many new exact solutions in terms of the Jacobi elliptic functions are obtained.
