just a riddle..

Posted in Uncategorized at 8:57 am by prabandana

Last time i had a quote boring morning with shower rain outside (cold is out of question, recently), and luckily i found my friend’s blog, arief updated with a riddle. Pretty nice riddle to spend the morning with, in my opinion..

here is the riddle:




There are no tricks, just pure
logic, so good luck and don’t give up.

  1. In a street there are five houses, painted five different colours.
  2. In each house lives a person of different nationality.
  3. These five homeowners each drink a different kind of beverage, smoke
    different brand of cigar and keep a different pet.



  1. The Brit lives in a red house.
  2. The Swede keeps dogs as pets.
  3. The Dane drinks tea.
  4. The Green house is next to, and on the left of the White house.
  5. The owner of the Green house drinks coffee.
  6. The person who smokes Pall Mall rears birds.
  7. The owner of the Yellow house smokes Dunhill.
  8. The man living in the centre house drinks milk.
  9. The Norwegian lives in the first house.
  10. The man who smokes Blends lives next to the one who keeps cats.
  11. The man who keeps horses lives next to the man who smokes Dunhill.
  12. The man who smokes Blue Master drinks beer.
  13. The German smokes Prince.
  14. The Norwegian lives next to the blue house.
  15. The man who smokes Blends has a neighbour who drinks water.



Dont take the last trashy comment too personally since its not confirmed.. just enjoy the riddle, spend your time with a coffee with you and find the fish !! (actually no one own the fish, its just an assumption of the animal not mentioned, and we have to guess its owner)..

To tell you frankly, i spent my first 10 minutes with no result but reading line per line.. I just noticed that every information is provided.. it was just so scattered..and we have to find and classify them. Then, we can decide a method to get the answer…. My answer isΒ  hereΒ 

I was just so interested in this riddle from some viewpoint (not trying to be wise)..Quite personal i think, but i found these moral:

* I was much more unsystematic before..and I found that my 1 year living in this country has shaped my self to be more sistematic person.. OK, i take it as a good effect , since to date, i ‘ve been thinking that too systematic wont be good, anyway..

* we have all the information around us.. its just need to be figured out..we also have to classify the information.. to make it more globally, the bad and good one..

* we need strategy, method before we act.. (my mentor always says this thing to me)

So how do you think about this riddle guys?? any comments?

    Akhirnya nge-blog juga si Dana ini. Bagus2..
    Menulis yang banyak Mas ya..
    Seperti kata Pak Ade di UPT Unpad, “Mesti dicoba mas ya…” πŸ˜€

    yeah, indeed…
    it looked like pretty tough at the first sight,
    but when we tried to do it step by step… one by one…
    the answer will be figured out…

    but, it’s not the same as the riddle problem in life…
    there are more unknown values which makes the problem more and more difficult…
    especially, when we’re searching for the candidates of our children’s mother… :))

    This is one simple example of data mining πŸ™‚

    @ahmad: ndak tahu nih, mad..ditungguin belon muncul2..lagi belanja kali..
    @jesse: wow, data mining!! mgkn bisa utk menjawab komennya jaya n ooks , Jes?? biar usaha mereka (sbnrnya kita semua sih :p) lebih efektif ??

    looking at the ‘orek2an’ nya mas dana nyelesein teka-teki nya dah bikin give up ikut coba2. hehe. btw selamat atas blog baru nya!

  11. jesse said,

    komen yg mana?
    udah dijawab sendiri kan πŸ™‚ ?

    intinya sih kalo ngerjain ini, ya klasifikasi tadi, kalo gw:
    1. bikin tabel 5×5, vertikal (urutan rumah), horizontal (kriteria2 isi rumah) -> bisa dibolak-balik.
    2. dari data yg ada, isi satu2 data yg udah pasti.
    3. dari data2 yg udah diisi coba diisi yg masih kosong, dalam proses ngisi, bisa keliatan, mana baris / kolom yg bisa diisi / ga.
    4. kalo gw, pertama dapet semua warna rumah.
    5. seterusnya gampang.

    Puzzle di atas bisa dikerjain cepet dgn trik ini.
    proses mikirnya aja spt data mining (kumpulin data, klasifikasi data).
    Tapi ga ada ngitung2 di puzzle itu πŸ™‚

  12. jesse said,

    From unknown values we could detect a pattern.
    If you put a lot of effort into it, the pattern will emerge.

    For your problem:
    Collect as many “data” as you can about your “object of interest”. πŸ™‚
    Assign all combinations of input to your object, process it, observe the output.
    The more you try & repeat, the more you would find the pattern.
    Maybe you could use a software to do that πŸ˜€

    The problem is, do we dare to assign an input that many ? πŸ™‚

    @jesse: hahaha.. bagus bagus jes…tuh jay dengerin jay!!

    In Artificial Intelligence: A Modern Approach book, that’s called Constraint Satisfaction Problem. I didn’t use formulas from that textbook to solve the problem, better using Microsoft Excel. πŸ˜€

  16. prabandana said,

    @yayan: yayan mo sasuga !!
    @ridwan: buset deh..aku dulu juga ada kuliah Introduction to AI. tapi kok perasaan ndak pernah dapet gini ya? kemana aja aku?? πŸ˜€

    Nyoba ngerjain teka-tekinya, yang pertama kelintas: kok yang ditanyain fish, jangan-jangan isi tebakannya ‘gak ada yang miara ikan tuh’ :D. Asalnya ngerjain di kertas mengeliminasi yang gak mungkin,,, tapi kepikiran pake mic. excel, tinggal ngegeser-geser kotak. Pertama nentuin dulu kata mana yang dah fix dan harus selalu satu kolom, terus tinggal digeser-geser …dipas-pasin ke baris yang masih kosong, ampe konstrain 5×5 nya cuman satu yang belum keisi :D.
    *padahal tadinya mu ngeresume jurnal… malahan jadi ngerjain ini, heheheh*
