the einstein riddle was posted on gaf a year or two ago already. it's just as dumb now as it was then

why can't you people find decent or interesting puzzles as well as you can find stupid flash animations?
 
With the help of Excel I solved the Einstein riddle. It took me quite a while, mostly because the number of clues and attributes.

Did any of you REALLY solve it or did you just Google the answer?

I really solved it. It took me like 5-10 minutes. I made 5 columns (1 for each house) and filled in the info bit by bit. Here are the steps I used. First the easy clues:

09. The Norwegian lives in the first house.... so I put "Norwegian" in column 1
14. The Norwegian lives next to the blue house...so I put "Blue" in column 2.
08. The man in the centre house drinks milk...so I put "Milk" in column 3.

Code:
HOUSE 1        HOUSE 2        HOUSE 3        HOUSE 4        HOUSE 5
-------------------------------------------------------------------
Norwegian
               Blue
                              Milk
04. The Green house is on the left of the White house... so either house 3 or 4 is green.
05. The owner of the Green house drinks coffee....therefore house 4 is green because the person who lives in house 3 drinks milk. This also means that house 5 is white:

Code:
HOUSE 1        HOUSE 2        HOUSE 3        HOUSE 4        HOUSE 5
-------------------------------------------------------------------
Norwegian
               Blue                          Green          White
                              Milk           Coffee
01. The Brit lives in a red house... Houses 2, 4, and 5 are Blue, Green, and White respectively so he doesn't live there. A Norwegian lives in house 1 therefore the Brit lives in house 3:

Code:
HOUSE 1        HOUSE 2        HOUSE 3        HOUSE 4        HOUSE 5
-------------------------------------------------------------------
Norwegian                     Brit
               Blue           Red            Green          White
                              Milk           Coffee
07. The owner of the Yellow house smokes Dunhill.... there is only one house left without a color and it is house 1. Furthermore we now know that the Norwegian smokes Dunhill:

Code:
HOUSE 1        HOUSE 2        HOUSE 3        HOUSE 4        HOUSE 5
-------------------------------------------------------------------
Norwegian                     Brit
Yellow         Blue           Red            Green          White
                              Milk           Coffee
Dunhill
11. The man who keeps horses lives next to the man who smokes Dunhill....therefore the man in the blue house keeps horses:

Code:
HOUSE 1        HOUSE 2        HOUSE 3        HOUSE 4        HOUSE 5
-------------------------------------------------------------------
Norwegian                     Brit
Yellow         Blue           Red            Green          White
                              Milk           Coffee
Dunhill
               Horses
03. The Dane drinks tea (therefore the Dane is in house 2 or 5)
12. The man who smokes Blue Master drinks beer (only houses 2 and 5 are possible again)

So either the man in house 2 drinks tea and the man in house 5 drinks beer or vice versa...we aren't sure which yet.

15. The man who smokes Blends has a neighbour who drinks water....the only house without a beverage is house 1.... which means he drinks water and house 2 smokes Blends. Since house 2 smokes blends we now know that the man who smokes Blue Master has to be in house 5 and that the Dane lives in house 2. That leaves us with:

Code:
HOUSE 1        HOUSE 2        HOUSE 3        HOUSE 4        HOUSE 5
-------------------------------------------------------------------
Norwegian      Dane           Brit
Yellow         Blue           Red            Green          White
Water          Tea            Milk           Coffee         Beer
Dunhill        Blends                                       Blue Master
               Horses
13. The German smokes Prince.... German lives house 4 because the person living in house 5 smokes Blue Master.
02. The Swede keeps dogs as pets.... house 5 since thats the only house without an nationality:

Code:
HOUSE 1        HOUSE 2        HOUSE 3        HOUSE 4        HOUSE 5
-------------------------------------------------------------------
Norwegian      Dane           Brit           German         Swede
Yellow         Blue           Red            Green          White
Water          Tea            Milk           Coffee         Beer
Dunhill        Blends                                       Blue Master
               Horses                                       Dogs
06. The person who smokes Pall Mall rears birds.... the only house without a brand of cigars is house 3.

Code:
HOUSE 1        HOUSE 2        HOUSE 3        HOUSE 4        HOUSE 5
-------------------------------------------------------------------
Norwegian      Dane           Brit           German         Swede
Yellow         Blue           Red            Green          White
Water          Tea            Milk           Coffee         Beer
Dunhill        Blends         Pall Mall      Prince         Blue Master
               Horses         Birds                         Dogs
10. The man who smokes Blends lives next to the one who keeps cats.... therefore the man in house one keeps cats.

Code:
HOUSE 1        HOUSE 2        HOUSE 3        HOUSE 4        HOUSE 5
-------------------------------------------------------------------
Norwegian      Dane           Brit           German         Swede
Yellow         Blue           Red            Green          White
Water          Tea            Milk           Coffee         Beer
Dunhill        Blends         Pall Mall      Prince         Blue Master
Cats           Horses         Birds                         Dogs

This leaves us with just one pet left...the fish. So the german owns the fish!

I'll take a stab at it. The answer is 99/1/0 (assuming we're working with dollars only).

A proposes to C: Vote with me and we'll split the $100 50/50

B makes a counter-offer to C: Vote with me and we'll split the $100 51/49 in your favor.

A makes C an even better offer.
B sweetens the deal even more.

This continues until C gets a 99/1 deal in his favor from B. A won't respond with a counter-offer since that would leave him with no money. Consequently, C accepts B's deal.

Ante Up
The Einstein one:
The Germans?

I forced myself to do it entirely in my head...

EDIT - I see this was already solved; nevertheless, it is a bit more difficult to do it without scrap paper.
 
There's so many stupid things with the original "riddle" it's ridiculous. The claim that these scoundrels who claim to be the smartest in the country care most about money is retarded, especially a sum as piddly as $100. A scoundrel claiming to be the smartest would be more concerned with outsmarting the outher three than claiming the money. But their motivation is supposed to be getting the most money, instead of outwitting the other two? Why mention that they are the smartest in the country then? The "A simple vote wins" doesn't cut it either, because there is nothing to win. The $100 has already been handed over. They can simply take it and not split it.
 
I solved the German one in about 5 seconds after reading it. I just knew for some reason that the German would have the fish.

If he's posted elsewhere on the forums and not in this thread, he should at least explain himself, if not face a ban.

Riddles deserve answers, and with the brain power on this forum, I see no real answer yet. We want an answer.
 
Wow,

This thread has gotten out of hand.

Please, allow me to explain.


Four years ago I came across this site:

http://www.srainc.com/people/brentr/riddles.html


Being a fan of riddles, I sat down and solved all but a few of them...forgetting about them months later before ever completing them all. Just recently I happened across the same site full of the same riddles. Again I sat down attempting to figure out all the riddles.

Now all of the riddles that I've solved (on the site thus far) have had logical answers that can be explained...they, to my knowledge, have all been real riddles. But there persist this one riddle in the bunch that I could NEVER answer (four years ago or today). After turning the problem over in my head for a couple days now; I gave up and saught advice by posting it on the forum in hopes that someone else had heard the riddle and knew the solution.

It wasn't my intent to plagiarize the riddle (I thought citing the author would be sufficient) , I only wanted the solution because I became frustrated with it.

Heh, that is the only site I came across that mentioned this riddle at all when I was trying to google the answer.

Edit:
HOLY SHIT, YOU KNOW WHAT? I THINK I MIGHT HAVE SOLVED THE RIDDLE.

but don't get your hopes up, I'm going off on a wild limb here.

Knowing most riddles are fucking annoying, and try to throw out red herrings about how to go about thinking of them, I reread the riddle to look for words that are ambiguous. I think I found it in the phrase "what will the outcome be?" Notice it does not say anything about how much money does each person end up with. As several people have theorized, once one person gets shut out of an offer, they will always counter offer with someone trying to get in on the offer. There will never be a solution. Since they care about money more than anything (even food and water) they will sit there and argue until they are dead. That is the outcome. The end.

Okay, so take that with a grain of salt. Also note that it is five thirty in the morning, I am pretty much exhausted and having crazy thoughts and I just want to have this riddle over with, with some sort of conclusion. I am sure someone will disprove me by the time I wake up, but it is enough so that I can go to sleep at ease for now.

No apologies? The compunctious nature of your reply betrays your internal regret. I demand you provide us with 3, nay, 5 completely original (and answerable) riddles as penance for this transgression. We, the GA masses are crass and petulant, and thirst for the blood our brothers in these black-hearted times.

EDIT: And after you present the 5, er, 7 golden riddles, you must chop this Ayn Rand book in 2. . .with a herring.
 
When I did the Einstein riddle, I thought that the green house just had to be somewhere to the left of the white, not necessarily right beside it. So I made it the house of the Norwegian, the yellow at the end, and the white the one in the middle. I worked it out, it works, and you get the Dane as being the owner of the fish.

I think it's pretty harsh to threaten a ban over a poorly attributed, really stupid not-really-riddle.
Nah, I just wanted to get the guy to own up to the real situation. I can see it worked. ;) Next time, you should do two things: cite your source, and make it CLEAR that you don't know the answer to the riddle so that people don't get frustrated.

I did a little bit more research on this "riddle," and I finally remembered what it sounded like: the so-called "Ultimatum Game" from experimental economics. For those of you who don't know the game, here is a good summary that I found:

http://neuroeconomics.typepad.com/neuroeconomics/2003/09/what_is_the_ult.html said:
What is the Ultimatum Game?

Take two people and tell them they have the opportunity to split $10. Furthermore, tell one person that, as first mover, they get to make a one time offer, and tell the other person that, as second mover, they get the opportunity to either accept or reject this offer. If the offer is rejected they both go home with zero.

This stylized negotiation was first studied by experimental economists in and economists got a surprise. Game theory predicts an unequal split favoring the person who gets to make the offer. After all if I offer a ($9, $1) split where you only get $1 you should take it since a dollar is better than nothing, but instead a majority of the offers are to split equally. Not a bad strategy if your partner is willing to reject unequal offers, and sometimes they do, but not all that often in the one-shot case.

Can fear of rejection explain the equal split offers? To answer this question, compare offers in the ultimatum game with offers in a simpler game called the dictator game. In the dictator game, the players who make the offers get to keep their share no matter what. Sure enough they make less equal offers, and keep more of the $10. Interesting, unlike the female capuchins in Sarah Brosnan and Frans de Waal’s study second movers always accepted their unequal monetary shares when it came time to collect in the dictator games, but by then first movers were long gone.
Now, there are a couple of interesting things to take away from the UG. First, there is NO optimal strategy for an individual player to pursue. (When both players in a game are "rational" -- technical term -- and have an optimal strategy, then the outcome of the game is entirely predictable.) Second, the psychological aspect led to 50/50 being the most likely outcome.

Interestingly enough, the three-person Ultimatum Game hasn't been studied very much -- probably because of complexity. You can read an interesting paper on the subject if you want.

Technically speaking, the "riddle" is NOT the same as the three-person UG: a UG, by definition, only offers the choices of accept or reject, not continued iterations. Still, I think it's pretty clear that there isn't a definitive solution to the problem.
