利用Monte Carlo进行数值积分(二) 进步空间很大的算法版本 话说去年6月的一个周六,我很无聊地发了一个帖子,写了一个自己感觉有点无聊的帖子。 Matlab多重积分的两种实现【从六重积分到一百重积分】 这个帖子居然成了我这种懒人随性瞎写的博文中阅读量、收藏量和评论量最多的一个。 很多人对我不写说明,不写例...
不过使用有限差分的最大优势在于计算delta,gamma,theta等希腊字母时,有现成的网格可以直接利用计算。四...

在对流过程中,作者使用了Heun方法来更精确地模拟粒子从 \( t+\Delta t \) 到\( t \) 的运动。这个方法通过计算粒子中间位置来获得最终近似值。对于扩散过程,他们通过邻近网格点的概率密度函数(PDF)来计算数学期望,从而在处理扩散过程时避免了使用蒙特卡罗方法进行采样。这里 p_{t}(\xi_{p,t}^{d,i}) 表...

Monte Carlo Simulation (MCS) was used to assess the properties of three structurally controlled reservoirs namely, Reservoir A, Reservoir B, and Reservoir C in the study area. Geologically plausible ranges specified by the mean and standard deviation values of the initial petrophysical parameters of ...
An error in the H-theorem in the two-weight \\delta f δ f \\delta f Monte Carlo method is found, which is caused by the weight spreading phenomenon inherent in the two-weight \\delta f δ f \\delta f method. It is demonstrated that the weight averaging method serves to restoring ...
