The discrete algorithm to solving Hamiltonian is just called sylleptic algorithm .

解哈密尔顿 方程的离散算法 就是 辛算法。

Sylleptic and Multisyllabic Structure-Preserving for 3-D Mixed Finite Element Method

三维混合有限元的 保辛及保多辛结构性质

One result of this article is the symplectic / multisymplectic structure preserving properties and it sure that our arithmetic is sylleptic algorithm .

这篇论文的一个重要结果就是方程离散后得到的保辛结构和保多辛结构的性质，说明了我们用的是 辛算法。
