发帖数: 727 | 2 According to my understanding, Quasi-Newton is faster since this algorithm
does not check total energy and only follows the direction of the steepest
descent (force)? So it only works well when the intial structure is near the
minimum. In this way, is this Quansi-Newton method (IBRION=1) can be used
for Transition State optimization?
Another question, both of the two methods will find their instantaneous
groundstate. In other words, local minimum. So how to make sure we can find
global minumem? ... 阅读全帖 |

But I have not learned functional analysis.

function is u(x,y, t). After discretizing in x- and y-direction, we will get
an ODE system: v'(t) = Av(t)+b(t) with initial condition. At this point,
some people suggest to split A into A = A0 + A1 + A2, and b(t) = b0 + b1 +
b2. Here, A0 and b0 come from the mixed derivative, A1 and b1 come from the
derivatives in x-direction, A2 and b2 come from the derivatives in y-
direction. Then using an implicit method to solve it.

我个人学习的一点心得,市场分析,无论是TA/FA/MA/Whatever A.
大部分人学到的都是方法,比如MACD金叉，balabala.
但其实最重要的是掌握方法论。
如果对这两个概念有混淆，举个例子，不知道大家有没有
读过麦肯锡的报告http://www.mckinseyquarterly.com/home.aspx
每个报告提出的解决方案是不一样的，也就是使用的方法是不一样的，
但麦肯锡核心价值，也就是其方法论是基本不变的。至于它的方法
