# 拉格朗日模拟这面的噪音目前有什么文章研究么？

• 欧拉欧拉那面由于已经在统计学方面已经处理过了，没有噪音。欧拉拉格朗日模拟这面目前有什么文章在处理么？找了找，还没看到。

As an alternative, Lagrangian methods ‘‘discretize” the density function into ‘‘parcels” that are simulated using Monte-Carlo methods. While quite accurate, as in any statistical approach, Lagrangian methods require a relatively large number of parcels to control statistical noise, and thus are computationally expensive.
