基于哈密顿动力系统新变分原理的保辛算法之三:数值算例
The symplectic algorithms for Hamiltonian dynamic systems based on a new variational principle part III:the numerical examples
摘要
Abstract
In References [1 ,2] ,four types of numerical algorithms were constructed for solving the Ham-iltonian dynamic systems and the symplectic property of the algorithms was proven .In this paper ,the de-tailed numerical performance of these four types of methods is discussed ,including the linear stability , the precision and the efficiency .关键词
