Abstract.Recently multisymplectic discretizations are attracting much attention, because they are the vigorous component of the structure-preserving algorithms. In this paper, the new development in the field of multisymplectic discretizations is systematically described and some very interesting new results are given. Multisymplectic and variational integrators are studied from a comparative point of view. The composition method for constructing higher order multisymplectic integrators is presented. The equivalence of variational integrators to multisymplectic integrators is proved.
