In this Letter, based on the idea of [YT. Gao, B. Tian, Comput. Phys. Commun. 133 (2001) 158], Jacobi elliptic function expansion method is improved and, with symbolic computation, some new soliton-like solutions are obtained for KdV equation with variable coefficient. Our method can also be used to solve other nonlinear partial differential equations. (c) 2005 Elsevier B.V. All rights reserved.
