报告摘要：In this talk, we consider the numerical methods preserving the energy evolution law of the stochastic Hamiltonian system, and these methods are able to reach strong convergence simultaneously based on some kinds of projection methods. The mean square convergence orders of these methods under certain conditions are given. And we also propose the variable parameter method by combining the parareal algorithm. Finally, numerical experiments are taken into account to show the superiority of our parareal algorithm.
