Abstract: The multi-symplectic formulations of the/"Good" Boussinesq equation were considered.For the multi-symplectic formulation, a new fifteen-point difference scheme which is equivalent to the multi-symplectic Preissman integrator was derived. The numerical experiments show that the multisymplectic scheme have excellent long-time numerical behavior.
