Sub look_up_18()
Sheet1.Select
Range("A1").Select
mmm = 0
NN = 18
For I1 = 1 To NN
For I2 = 1 To NN
For I3 = 1 To NN
For I4 = 1 To NN
Sum = I1 + I2 + I3 + I4
prod = (I1 - I2) * (I1 - I3) * (I1 - I4) * (I2 - I3) * (I2 - I4) *
(I3 - I4)
If (Sum = NN) And (prod <> 0) Then
mmm = mmm + 1
ActiveCell.Offset(mmm, 1) = mmm
ActiveCell.Offset(mmm, 2) = I1

发帖数: 956 | 11 试了一下，把10到20之间的数都找一遍：
Sub look_up_18()
Sheet1.Select
Range("A1").Select
mmm = 0
For NN = 9 To 20
NNN = 0
For I1 = 1 To NN
For I2 = I1 + 1 To NN
For I3 = I2 + 1 To NN
For I4 = I3 + 1 To NN
Sum = I1 + I2 + I3 + I4
prod = (I1 - I2) * (I1 - I3) * (I1 - I4) * (I2 - I3) * (I2 - I4) *
(I3 - I4)
If (Sum = NN) And (prod <> 0) Then
mmm = mmm + 1
NNN = NNN + 1
ActiveCell.Offset(mmm, 3) = NNN

发帖数: 451 | 22 It really depends on the model assumption and what the true stock market
behavior is.
If we assume on day t, the return of index is X_t, which are mean zero,
independent RV, then the expected return over T days will be
E( \prod (1+X_t) ) = 1.0 === E( \prod( 1 + 3*X_t ) ) (expectation)
This shows that if we are in an ideal/theoreticaly world where stock markets
are independent from day to day, then 3X leverage is fine to hold. The main
problem of the above assumption is that X_t will not be ind... 阅读全帖 |

发帖数: 61690 | 24 Two weeks after his vice-presidential bid ended, Rep. Paul Ryan (R-Wisc.)
ran into an old friend, Rep. Luis Guitierrez (D-Ill.), and prodded him to
restart his effort at comprehensive immigration legislation. His argument
came from a religious and economic foundation.
“You’re a Catholic, I’m a Catholic, we cannot have a permanent underclass
of Americans exploited in America,” Ryan told Guitierrez, according to the
Democrat’s recollection of the November 2012 discussion.
Since then, Ryan has walk... 阅读全帖 |

标 题: 今天早上听新闻发现,FB居然真的成了高科技公司
发信站: BBS 未名空间站 (Sat Oct 6 13:52:05 2012, 美东)
1.dc.据说FB的DC是目前世界最先进的,比平均水平节能30%以上,超过google的了。而且
这个节能DC居然是FB自己设计的。
2.这个真的是世界独一无二.FB的程序是世界上为一个PROD运行，TEST调试，PROD修复
三个并行同时运行的。就是说FB的product可以做到online,test,debug at the same
time.而且FB的系统是世界上唯一一个在运行中允许用户contribute info的系统。这个
比较神奇啊。
3.嗯据说，FB现在处理的问题如果单独难处来,可以再开一个CS的分支了。 |

发帖数: 29576 | 44 Gonzalo Jara to be sold by angry Mainz: The prod was bad, but the threatrics
were worse
Mainz sporting director Christian Heidel couldn’t hide his anger after
watching the episode.
‘He knows that if an offer comes, he can go,’ Heidel told Bild.
‘We do not tolerate that. More than the prod, however, it is what comes
afterwards that makes me angry. I hate theatrics more than anything.’
Jara’s career is littered with disciplinary problems and he’s had spells
at Brighton and Nottingham Forest as wel... 阅读全帖 |
