Title :
Discrete Midpoint-Type Variational Integration
Abstract :
In this paper, we will study discretization of variational integration, especially midpoint-type variational integration, which preserves the symplecticity property of Hamiltonian systems. And numerical experiments will show us the superiority of the constructed variational integration.
