前两日在纽约客上看到这篇文章:better all the time
http://www.newyorker.com/magazine/2014/11/10/better-time
主题应该是最后那句话,“the way to improve the way your perform is to
improve the way you train." 文中举了很多例子来支持这一结论。比如说运动员们以
前认为只要被选为职业球员就表明自己技术上已经登顶了,训练也只是为了培训队员间
的配合,而现在,他们周围都有一个很强的团队,体能训练师,理疗师,营养师以及各

行车运动员“was the ultimate product of an elaborate and finely tuned system
designed to create the best cyclist possible.” 而教育届也应该这样,对教师
不断地进行培训,老师的教学水平上升了,才能更好的指导学生。

Determinism, free will and compatibilism
by Tim Harding
The idea that the future is already determined is known in philosophy as
determinism. There are various definitions of determinism available; but in
this essay, I shall use the Stanford Encyclopedia of Philosophy definition,
which is ‘the metaphysical thesis that the facts of the past, in
conjunction with the laws of nature, entail every truth about the future’ (
McKenna, 2009:1.3).
This idea presents a difficult problem for the concept of... 阅读全帖

the cauchy-schwartz inequality doesn't help at this time
since it should be <=1. The hint is the solutions should
related to the eigenvalue and eigenvectors.
From the previous question, we know that
the min of a'*S_11*a is the smallest eigenvalues of S_11
and the min of b*'S_22 is the smallest eigenvalues of S_22
if we have the constrains of a'a=1 and b'b=1
But here we don't have the constrains and
I don't know how to approach the numerator either. :(
Thanks a lot though.

Generally, for unconstrained minimization problem(all maximization could be
easily changed into min , and nearly all constrained problem could be
transfered into a unconstrained problem-------- < > constrains could be
treated as domain )
Among them, the Newton's search 和steepest descent are well-known.

1. 你把问题扯远了,我们argure的是C# 加入 constrain 使得语言更加OO了。另外OO
的基本核心思想是封装,你所说的这些优点难道是OO特有的,难道过程式语言、函式语
言就没有,linux kernel算大工程不?虽然OO好用,但没有必要捧到天上去
2. 正如我所说过的,造成你所谓的*bussiness* error 还是syntax error,根本原因
在于库的设计者出错了。你前面的举的例子无非在说明constrain的作用,是模板库的

Your timing is bad. I suspect you are contraining too much or too little.
How did you specify your constraints? Do you have a .sdc file or you set the
constraints through Quartus GUI?
You need to constrain every signal. Otherwise, the tool will do whatever it
wants to do. You need to properly constrain signals which are really
critical. For signals where timing doesn't matter, just specify a very loose
constraint.

来自主题: Mathematics版 - question about Principal Component Analysis
其实应该算是 constrained principal component analysis. 如果我想把第一个
component定为一个 constant vector,然后依次求后面的component. 那么第二个
component 就应该是下面这个条件极值的解:
max_{x} x'W x
s.t. x'x = 1
x_{1}' x = 0
x_{1} 就是那个constant vector,W是一个正定矩阵。
请问这样的问题有没有什么简便的算法,或是有没有那个计算软件或者已经写好的程序
可以解这个问题。我试过用MATLAB里面的constrained minimizer 来解,不work。提前
