标 题: 称球问题
发信站: 水木社区 (Tue Aug 26 09:46:11 2008), 站内
有6个球,三个各重a克,另外三个各重b克,b>a,但不知道具体各是多少
用天平称三次,确定哪三个是重球,哪三个是轻球。
每次两边放相同个数的球,每次称量怎么选球无视前面称量的结果。

第8条,应该对多数人有效。
中国式的悲哀
1. 55岁的周润发宣布死后将捐出99%的财产,什么都不想带走。作家顾晓军评论道:千
万不要捐到大陆来,不要害了无辜的官员。
2. 发改委成立至今只做过两件事:1)涨价,2)替涨价辩护。
3. 目前中国有效的反腐手段有:1)夫妻反目;2)家中被盗;3)意外事故;4)情人
举报;5)网民诅咒。
4. 国外奶粉热销中国的原因:1)没有三聚氰胺;2)如果有,可以索赔巨款;3)如果
索赔不成,不会进监狱。
5. 1955年中国的人均收入是韩国的3.2倍,日本的1.1倍。但经过50多年"翻天覆地"的
增长,2008年中国的人均收入是日本的3%,韩国7%,但韩国、日本从来没宣布自己经济
怎么翻番,只有中国是天天说自己翻了很多番。
6. 中国人固有一死,或死于地沟油,或死于石灰面粉,或死于结石奶粉,或死于毒疫
苗,或死于危房,或死于拆迁,或死于日记,或死于酒色,或死于宝马车轮下……中国
人口号:一天一杯牛奶,震惊一个民族!死并不可怕,可怕的是你根本不知道自己是怎
么死的!
7. 中国不一定是和邻国土地争端最多的国家,但肯定是和本国公民土地争端最多的国
家。
8. 在谈所谓大国崛起之时,请扪心自问:你的收入崛起没有、你的住房面积崛起没有
、你的护照免签国家数量崛起没有、你的食品安全崛起没有、你的医保社保崛起。。没
有,如果都没有,那么大国再崛起关你P事。
9. 日本人冈本真夜1997年的一首歌无耻地抄袭了我们2010年世博会的会歌,太可恶了!!
10. 什么是奇迹?我建了一座豆腐渣大楼,然后雇了150个短工装修,很多人说这房子
容易塌,我充耳不闻。结果「哗啦」的塌了,把他们埋在废墟里整整八天八夜,我找人
挖开塌坍时,有一百多人活着。这是个奇迹,更奇迹的是我他妈不但无罪,还成了救人
的大英雄!
11. 中国统计局宣布:中国城市人均月收入已突破9000人民币大关。拖祖国后腿的同志
们请自觉转发。” 看到这个消息我不禁黯然神伤,我无颜转发,仔细算算,我何止才
拖了祖国的大腿,我都拖到祖国的大腿根,活着买不起房,死了买不起墓,还是买张动
车票吧,包埋哦,亲!

在Matlab 1.6下运行程序是出现如下错误:
failed to find MEX-File on path: sortrowsc.dll
而sortrowsc.dll确实存在于工作目录下(c:\MyWorkSpace),环境变量也设好了。在
运行mglinstaller。exe后生成的那个目录(bin\win32)下也放了这个sortrowsc.dll
按照如下说法,貌似这样做就 足够了:
http://www.mathworks.com/support/solutions/en/data/1-19DWR/inde
Solution:
This is a bug in the MGLINSTALLER with the C/C++ Math Library 2.2. This
problem has been fixed in MATLAB C/C++ Math Library 2.4 (R13).
If you are using a previous version, see the information below:
This error occurs because the client computer does not have the MEX-file
sortrowsc.dll. This MEX-file does not come packaged with the mglinstaller.
In order to distribute a stand-alone application that calls sort rows,
sortrowsc.dll and/or sortcellchar.dll, must also be distributed. The
libraries can be placed in the same directory as the executable or in the
bin\win32 directory created by the MGLINSTALLER.
不过还是不行。求大虾们指点。现在一个在matlab下运行的library

各位大牛,
拜托有经验之谈的朋友帮忙拿个主意:
4年工作经验: 10% wasterwater process design, 10% water main replacement
design, 80% water resource, wastewater collection system design, SSES
美国Master,国内本科,Both环境
请问选Environmental的PE有利还是Civil(am)+Water Resource/Environment(pm)有利?
多谢!

it would be a much simpler problem without the last constraint:P
i can prove that every time you have to put two balls on each side, but
simple-minded construction seems not working. does such a solution exist?

我这会算是小将了一把

u can compare 2 references for these 2 type of exams.
I got an impression that exam for Env. PE might be better in ur case.
it is not very hard to pass such exam for Chinese graduates.

first, hero080, could you confirm whether the solution exists or not?

WARNING: for completeness, i spent some time writing down the proof, but it'
s pretty messy, so most of you might want to skip the details.
here is a sketch:
there are 3 outcomes for each weighing:
left side heavier (L), balanced (E), right side heavier (R)
so total of 3*3*3=27 outcomes.
note there are only C(6,3)=20 ways of picking 3 balls out of 6.
let's label the balls from 1 to 6. if there exists a way to fulfill the
req

Wow ... Still use Matlab version 1.6??? Can you upgrade the version? That
would be the most convenient way I think.

the question should be: "if not exist, prove it".
Actually personally I believe that it doesn't exist.
I don't have time to view your answer now. I'll check it tomorrow.

i c. good to know that we are on the same boat.
unfortunately, so far all i have been doing is just exhausting all the
possibilities...
