摘　　要：We investigate the multi-symplectic Euler-box scheme for the nonlinear Schroedinger equation. Two new simple semi-explicit scheme are derived. A composition scheme based on the new derived schemes is also discussed. Some numerical results are reported to illustrate the efficiency of the new schemes.We investigate the multi-symplectic Euler-box scheme for the nonlinear Schroedinger equation.
