A good one:

You are in a prison. There are 3 doors, and a ghost standing in the middle of the prison. He says one of the doors is the way to freedom while the other two lead to death. You get to ask only one question. He will only answer with YES or NO. All he says is truth. What do you ask to find the door to freedom?

>>207623
I'll bite:

Information Theory says there's one bit of entropy in the ghost's answer, but 1.6 bits of entropy in the answer you must give, so no matter how cleverly or convolutedly you phrase your question, you will always be given less entropy than you need to provide, and thus the answer can never, *ever* inform your decision.

I'm guessing the trick is some kind of cheaty way of squeezing out a third possible answer, probably something to do with halting, along the lines of "if the door on the left is safe, please say yes; if the door on the right is safe please say no; otherwise please tell me the word that contradicts what you're about to say"

>>207644
Go on, you'e more or less on the right but don't overly complicate yourself

Gimme a definitive answer

>>207623
death is freedom

>>207644
Write 'yes' on one door, 'no' on another, and nothing on the final door.
>What did I write on the door that leads to freedom?
Ghost has to tell the truth, so he can't answer if it's the nothing door. Otherwise, yes or no it is.

>>207807
You're not allowed to write/use anything though

You're only able to ask a question

>>207909
>>207807
So phrase it as a question.

It was already solved in >>207644.

Everything after is just donkey work: construct a machine that considers the three doors and returns yes, returns no, or never halts, then ask the ghost (or "oracle" as he'd be known in CS) what the machine would do.

The crux was tricking the problem statement into giving you three possible replies instead of two. My guess was that it involved halting, and >>207807 and >>207646 confirm this.

>>207924
>The crux was tricking the problem statement into giving you three possible replies instead of two
This is right, the rest of your reasoning is wrong

You're only able to ask one question and only one, you don't have to do/manipulate/build anything else

And i consider his reasoning >>207644 to be wrong as well, because he is not asking just one question

>>207955
>you don't have to do/manipulate/build anything else
We're talking about "machine" in the "Turing Machine" sense, you silly. It's a thought experiment, not an actual machine.

Like I said before, I consider the problem solved, and boiling down the question to the exact specific form that seems to be required to be donkey work.

Turing equivalence says it can be done, and that's good enough for me.

>>207963
>I consider the problem solved, and boiling down the question to the exact specific form that seems to be required to be donkey work
That's a very lazy answer. If you're not formulating a question, i don't consider this riddle solved. If you're so smart, you should be able to come up with one

>if the door on the left is safe, please say yes; if the door on the right is safe please say no; otherwise please tell me the word that contradicts what you're about to say
I really don't see how that solves anything, that looks like a three questions in one to me, not working

>>207975
I guess we'll have to disagree, then.

The meat of the "puzzle" was that you have to exploit halting to cheat your way around the stated restrictions; if I truly cared about the exact phrasing you were after, I'd just google it.

>>208010
When you solve a math problem during an exam, do you say 'we just use this and this, the rest is donkey work' without elaborating and giving a concrete answer? I don't think so

What you just gave me is a vague explanation, not an actual answer

>>208012
I don't know where you learned math, but actually yes, if you solve the crux of the matter, you can get the donkey-work wrong or even not do it at all and still get most of the marks.

This is why they teach you, right from kindergarten, to *show your working*.

>>208012
I'm sorry no-one sucked your dick over this; personally I felt gypped because I was expecting the solution to be a clever algorithm that made use of non-obvious resources and covered all the corner cases (like the prisoners and the two levers), but instead ten seconds of elementary information theory was sufficient to prove that a clever technique could never work and the only "solution" was to cheat.

So having told you what the cheat is, I consider the matter done.

"If I assume the doors are marked 1, 2, 3, what answer would I get if I gave the number assigned to the safe door to the program 'while(n!=3);return(n==2?"yes":"no");' ?".

I hope that means something else in Swiss, because in English it means "shit university".

But yes, games like Layton and Braid can suck my dick, because the no-effort solution is, in every case, to evaluate the entire search space then walk it. There's no actual thinking required, just try every answer until you give it the one it wants.

>>208024
You're twisting the premise of what is supposed to be a very simple and plain riddle. What they mean by 'He will only answer with YES or NO' is that he can only give an affirmation or a negation, imagine the ghost nodding his head 'Yes' or 'No'

So your answer is wrong. That's the type of question you'd get back in the middle ages, where there were no concept of algorithm i presume

Stop with the mental masturbation, will ya? You didn't solve the puzzle

You're not allowed to write anything. The only thing you can do is ask a question and believe me, it's possible, but i admit it is kinda hard to find. It's a logic based question

What 'You get to ask only one question' means is that it's your only course of action

I was talking about programming algorithms, dumbass
>Yet "He will only answer with YES or NO" doesn't mean "He will only answer with YES or NO".
Alright, i'll spell it out for you, 'He will only answer with YES or NO' actually means there are objectively 3 answers he can give, 'Yes' or 'No' if he can answer the question and 'no answer', meaning he stays silent, if he can't

The trick is finding a question (in plain english, no programming nonsense) that fits this purpose

>"If I assume the doors are marked 1, 2, 3, what answer would I get if I gave the number assigned to the safe door to the program 'while(n!=3);return(n==2?"yes":"no");' ?"
And no, this doesn't work

>I'm guessing the trick is some kind of cheaty way of squeezing out a third possible answer, probably something to do with halting
is saying exactly the same thing as what you just "spelled out"?

You claim to have gone to an Institute of Technology, but you don't recognise the Halting Problem when you see it? Did you just suck your cock whenever informatics came up?

Once you work out that you're allowed to misinterpret "the answer is only yes/no" into "the answer is only yes/no/spin"*, you've done the interesting part. The actual question isn't interesting, because there's an infinity of different ways you could ask it, and they're all variations on a question that everyone learns the first time they encounter a proof of the Halting Problem.

I don't keep giving you pseudocode to wind you up, I keep giving you pseudocode because English and pseudocode are Turing equivalent, and if you were paying attention during the degree you claim to have, you would know what this entails and wouldn't be picking hairs over a sentence.

* and I'm with >>208051 on this one: "you can make him give a third answer even though it explicitly says he gives two answers" is just as horrendous a mangling of the problem statement as "you can use a pen because it doesn't say you can't".

You're one delusional and narcissistic individual, you keep talking in fancy terms because you think it makes you look good and above the rest while most people on this chat don't understand the fuck you're saying.

If you were as smart as you'd like people to think, you'd go along for the fun of it and actually give an instance of the answer you so arrogantly dismiss as useless. You ask for riddles and then you piss on them when they don't fit your inflated ego.

Here's the official answer in pic related, because i feel we're not going anywhere. The answer I had personally come up with was 'Does the door on the right of the good door have a door on its right?'

>Did you just suck your cock whenever informatics came up?

>>208104
>actually give an instance of the answer you so arrogantly dismiss as useless
I gave several.
All the answers everyone in this thread gave reduce to each other; this is year-one stuff for any degree with the word "science" or "engineering" in the title.

As to why it's a shit puzzle:
>*smartarse question*
>ghost says nothing
>you go through rightmost door, die
>two hours later, ghost says "yes"

You just got killed by halting, something you should have learned about in Computability 101. If you allow "no answer" as an answer, you violate the tacit constraint that the ghost has to give an answer in a reasonable time. Which was as valid a tacit constraint as "you can't write on the doors".

I'll bite. The scenario does not describe when you have to ask the question. It does not describe when the ghost has to answer it. It does not describe any sort of restriction that is related to time. This is a relatively significant loophole. The speed at which a YES or NO answer is delivered will cause said answer to carry additional information. For example if you hesitate to say YES or NO to something then this hesitation carried more information than the answer alone. This sort of principle can be used in this riddle.

As far as I know you can simply ask the ghost "please say YES after after one minute if the first door leads to freedom, after 10 minutes if the second door leads to freedom or after 100 minutes if the third door leads to freedom". The timing of the response will give you the additional information necessary to solve this problem. You don't even need YES or NO, just one word is enough.

If there is any concern that this sounds too much like asking the ghost a request than a question, something which is not very well defined in the problem, then you just need to reformulate the question. You can ask "If you answer this question with YES after 1 minute if the first door leads to freedom, after 10 minutes if the second door leads to freedom or after 100 minutes if the third door leads to freedom, would that give me the correct answer?"

The ghost must answer YES after this statement and the ghost must answer after the proper amount of time because otherwise the answer would be a lie. The ghost is not allowed to die.

>middle door is freedom door
>you ask "if I go through the middle door and die, would it have been a better choice to have chosen the one on the left"
>ghost says "no"
Then EITHER:
>you go through middle door, get married, have a few kids, buysome stuff, retire to Florida, and die
>go through left door and die (chances are you'll do this, and feel smug whilst you do)
>go through right door and die
>in all situations, left door is not a better choice than middle door, so ghost didn't lie

Thus the "solution" only works if the freedom door is not the middle door, so it is not a solution.

Killed by a ghost's ability to reason about hypotheticals.

Here's an actually good prisoner puzzle:

The warden meets with 23 new prisoners when they arrive. He tells them, "You may meet today and plan a strategy. But after today, you will be in isolated cells and will have no communication with one another.

"In the prison there is a switch room which contains two light switches labeled A and B, each of which can be in either the 'on' or the 'off' position. BOTH SWITCHES ARE IN THEIR OFF POSITIONS NOW.* The switches are not connected to anything.

"After today, from time to time whenever I feel so inclined, I will select one prisoner at random and escort him to the switch room. This prisoner will select one of the two switches and reverse its position. He must move one, but only one of the switches. He can't move both but he can't move none either. Then he'll be led back to his cell."

"No one else will enter the switch room until I lead the next prisoner there, and he'll be instructed to do the same thing. I'm going to choose prisoners at random. I may choose the same guy three times in a row, or I may jump around and come back."

"But, given enough time, everyone will eventually visit the switch room as many times as everyone else. At any time any one of you may declare to me, 'We have all visited the switch room.'

"If it is true, then you will all be set free. If it is false, and somebody has not yet visited the switch room, you will be fed to the alligators."

There is a strategy you can come up with in the strategy meeting that gives the correct answer 100% of the time and guarantees you an alligator-free future. It doesn't rely on tricking reinterpretating the question or on an unorthodox interpretation of what the words "only" or "answer" mean.

*this puzzle is actually a simplified variant of a harder puzzle. In the harder one, you don't know how the switches are set.

>>208121
> you're more asking a request than a question...
And I just describe how to turn my answer in a more question-like formula in case you tried to use this weak excuse. Did you stop reading? Sharing riddles is very fun but it can also be infuriating when someone behaves as if their answer is the only answer. If you cannot argue against this answer then it is equally valid, regardless of whether it is the answer you had in mind.

>>208128
>middle door is freedom door
>you ask "if I go through the middle door and die, would it have been a better choice to have chosen the one on the left"
>ghost says "no"
The ghost can't lie so he won't answer, hence the middle door is the good one

>Thus the "solution" only works if the freedom door is not the middle door, so it is not a solution
It does
>>208131
That's actually the right answer! I'm not even kidding :/
>>208134
I've never seen this one, i'll give it a try :)

>>208211
If you go through the middle door, you'll die. Unless you're Connor MacLeod of the clan MacLeod.

You'll die much later, after a more fulfilling life, therefore picking a different door where you'd die much earlier wouldn't be a better decision.

In any case, you can hardly argue that the ghost can't consider the hypotheticals of you choosing a door and you dying, when you're expressly asking him to consider the hypothetical of you choosing a different door.

Plus there's also the "now the ghost isn't obligated to answer in a timely manner, so he just says 'yes' after you assumed he wasn't saying anything" problem the other solutions also have.

>>208139
>>208215
Both of you, let me think

>>208139
>If you answer this question with YES after 1 minute if the first door leads to freedom, after 10 minutes if the second door leads to freedom or after 100 minutes if the third door leads to freedom, would that give me the correct answer?
Your answer is interesting but it's still wrong. Basically, what you're asking the ghost is 'If you do as i say, would that give me the answer?' but the ghost can say 'Yes' without lying, because your question asks about a hypothetical situation, get what i mean?

If he says says 'Yes', it would mean 'Yes, IF i do as you say, you'll get the right answer' but he doesn't have to abide.

It's like me asking you 'If you shoot me, will i die?'. Even if you say 'Yes', you don't have to shoot me. Hope that answers your question.

Btw, your sentence reminded me of the Pinocchio problem, do you know it? What would happen if Pinocchio said 'My nose will grow now'?

>>208215
You misunderstand the answer. If the middle door is the good one, then obviously the others lead to your death and none of then are a better choice in the hypothesis, so the ghost can't answer.

Then of course if the middle door leads to your death, then the ghost can answer 'Yes' or 'No'

>>208227
>obviously the others lead to your death and none of then are a better choice in the hypothesis
Then the ghost has a clear answer: NO, the left door would not have been a better choice.

Remember, the question is not "left or right", but "yes or no".

>>208227
I am not asking an hypothetical question. Compare these two sentence structures:

>"If I ask you the following question, would you answer X"
>"If you answer THIS question with X, would that give me the correct answer?"

The second example is not an hypothetical question. It is that very question that the ghost is addressing. The ghost cannot bluntly answer NO because it's true that the timing of their answer would reveal the correct door. The ghost cannot say YES immediately after 1 second because then their answer does not reveal the correct door and therefore their YES is a lie. The ghost can safely answer that question without lying or creating any paradox but the timing of their answer will determine whether their answer is acceptable.

It is indeed similar to the Pinocchio problem since both setup involve a self-reference. A statement or question with a self-reference can can lead to a paradox but it is not always the case. You can carefully say a sentence with self-reference without causing any paradox and you can carefully ask a question with a self-referencing answer which doesn't break any law of causality. Consider how "this sentence is a lie" is paradoxal but "this sentence is not a lie" is not. Likewise, Pinocchio can safely say "This sentence will not make my nose grow" and I can safely ask the ghost my question.

>>208275
>The ghost can safely answer that question without lying or creating any paradox but the timing of their answer will determine whether their answer is acceptable.
Note that if the ghost doesn't like you, he's free to just never reply ever.

the supposed official answer does not work?
>"If I go through the middle door and die, would the left door have been a better choice?"

The way I read it, this *is* a hypothetical. Let's assume the middle door is actually the correct one. Then the question reads as "But if I still die, would either of the other doors have been better?" And the obvious answer is a resounding "no", not a "stay silent because cannot lie". Under the assumption that the middle one is death, the others are not better, because they are death regardless.

To me this meaning is pretty clear. >>208275 seems to maybe disagree? So at best the meaning is ambiguous which would not help in this scenario.

There's nothing to indicate that the hypothetical is only "if i go through the middle door", rather than "if i go through the middle door and die".

>>209110
>>209140
not bad, but the second switch is necessary in your solution since the prisoners *have* to reverse at least one switch. it doesn't carry information, but it's necessary.

your solution doesn't work though. you can't guarantee a designated counter visits often enough. they are only guaranteed that they all visit an equal number of times. so if that number is 1 (or anything below 23) the designated counting method would fail. but even if the number is 50 it would potentially fail, because everyone could theoretically do all their 50 before the counting guy ever gets in there. then he finds the switch up, counts 1 and consecutively visits 49 times with the switch down. then everyone was in there 50 times and nobody knows shit for sure.

>>209435
Damn, you are correct. Seems my brain can't handle puzzles at 3am brain like it used to. Sorry for any confusion my posts have caused.

>>208134
the isolation only takes place "after today" so how about the prisoners hold today's strategy meeting in the switch room?

feels like a cop-out, but the wording permits it. especially given how often it's specified that various rules only come into effect "after today".

with only 4 bits of communication available they can't reliably count to 23 otherwise. especially not given the rule that forces exactly one switch and with the randomness of prisoner selection. whatever the solution is would have to work at least for all multiples of 23 visits, but at the same time no prisoner could ever be sure that the visitations are over. how to differentiate between 23 visits total and 23 visits by the same person? and the warden could always start another round of 23 visits.

or the warden could be a dick and do 1,000 visits of each prisoner one after the other with 5 days between them. he only promises "given enough time" they'd visit equal times, not that it will fall within their lifetime. so an abstract strategy that works 100% of the time doesn't necessarily set them free. note that he only promises them "an alligator-free future". this promise could be kept with the strategy of never claiming everyone has visited. they'd be incarcerated indefinitely, but they'd never be fed to the alligators. he never promises freedom.

>>208134
oh, hold on, i think i just figured out how to do it without holding the meeting in the switch room on the first day. the warden guarantees "no one else will enter the switch room", promising to leave the room in an unchanged state. so each prisoner could self-inflict a wound and put a mark in blood on the wall the very first time they visit the room. since only prisoners enter, it'd never be cleaned. the prisoner who visits for the first time and counts 22 other marks can then tell the warden that everyone has been in there, setting them all free.

>>209472
I thought practically the same thing, each prisoner should leave a physical mark when they visit the room for the first time but I'm not sure that's how the puzzle is supposed to be solved...

>rather than "if i go through the middle door and die".
Have you worked out a way to go through a door and not die?

Maybe you should tell Elon Musk.

In any case, "is x better than y" is never undefined for any value of x or y. x is either better than y (yes), or not better than y (no). If the answer to that question is not "yes" then it is always "no".

I believe you, it feels there's some complex algorithm involved though...

Will give it some more thought :/

>>209752
i'm sorry, but i'm calling bullshit. i'll break it down and you can tell me where i went wrong or admit to masteful trolling.

>full premises
23 prisoners total (the number is known to everyone involved)
two unconnected switches labeled A and B with "on" and "off" states each
A is currently off
B is currently off
randomly selected prisoners flip exactly one switch at random times
everyone will visit the switches an equal amount of times, but at least once (since correct answer is guaranteed)
at least 1 prisoner needs to be able to safely tell once everyone has visited the switches at least once
the prisoners *only* communicate via the switches
the game is potentially played for literally an infinite timespan (the only way to guarantee both truly "random selection" and "everyone will visit as many times as everyone else")
if his random selection process happens to have sent every prisoner to the switches an equal amount of times, the warden could simply stop sending prisoners. (nothing in the text indicates he's forced to select prisoners since he only does it "whenever i feel so inclined"). no individual prisoner could ever know whether the warden stopped or whether the random selection only happens to choose other prisoners.

>>209959

>simplification
infinity is always a pain in the ass and unless an actually infinite amount of rounds would be played, the odds would only ever probabalistically approach certainty (but the warden promises 100% certainty). so let's disregard that for now.

let's look at a valid subset: the warden's RNG spits out every prisoner's number exactly once. then the warden chooses to stop. since this could actually happen (unlikely but possible), the prisoners' algorithm has to work in this scenario.

the prisoners' communication via switches has an upper bound of 2 bits of information (00,01,10,11). in practice it is much much lower. any prisoner cannot pick a state freely but must flip exactly one switch given a previous state. the initial state 00 should be unavailable since any prisoner finding 00 would think he's the first to visit the room. the 23rd prisoner needs to find a unique state, so he can with certainty tell he is indeed the 23rd. since none of the prisoners visit the room twice, he's the only one who can verifiably tell everyone has been to the room (only he can possibly know about him having been there). this already only leaves 1 bit of information to safely count to 22. but how would the 22nd prisoner know he's the 22nd and must set the special state for the 23rd? only if he himself has a unique state, etc. it's completely impossible to count to 23 with only 2 bits of information and a non-recurring initial state. they can't even decide on a cycle (00-01-11-10-00-01-ect) since they would have no way to keeping track of the number of cycles.

i don't think this is possible to solve. even if they knew they'd visit the room exactly once, then never again, they'd have no way of keeping track.
it's the randomness of time that screws everyone over. if there was a rule stating that the warden would have to send exactly one prisoner to the switches every day this could be solvable? but not with a completely random amount of time between visits.

no, because he guarantees there is a strategy that will allow the prisoners to give the answer correctly at some time in the future, implying that at some point everyone will have visited the room at least once. if they stay in their cells forever, he lied to them and they can never set themselves free.

>>209989
Nope, try again :^)

>>209746
Time?

I wouldn't really say that time bites steel or grinds stone because there are other forces of the universe that act on those objects. Sure everything has a limited time for existing but time wouldn't slay a king another creature would.

>>210079
Correct answer! Well done, anon :^)

But don't ask me, it's a riddle from the book 'the Hobbit'

How do plants devour time?
I think you meant a thing that devours all things

>>210098
Nope. All things that are born have a finite amount of time until they die. Hence as they live, you could say they 'eat' their time up. It's a metaphor

Here's another one:

"In a riddle whose only answer is chess, what is the only word that is prohibited?"

I actually don't know the answer to this one, as i wanted to try it out myself too :/

>>210099
This riddle makes no sense to me. The English language has many different ways to say the same thing. You can't limit any words because you can just use others along with it to end up with the same meaning.

Still I'm going to attempt to throw some sort of logic at this. I'll say the only word that is prohibited is "me" The riddle then becomes "What board game is played on an 8x8 checker pattern board where you can say king?"

You can't say king "me" because then the answer would become checkers. But this logic falls through when you can just rephrase the riddle "What board game is played with me and an opponent on a ..."

I was actually going to guess at Time but it just seemed such a generic answer I figured it'd be wrong

>>209746
What have I got in my pocket?

>>210313
You mean you got something in your front pocket for me?

more bumps

I found the answer, it was 'chess'. Which is paradoxical if we consider the riddle, but it was meant to be that way apparently. This was taken from the 'The Garden of Forking Paths' by Jorge Luis Borges btw

Here's another famous riddle (i have a whole list of them):

"There is a house. A person enters this house blind but exits it seeing. What is it?"

I accidentally saw the answer of this one, so it's all yours :/

>>210319
Why don't you reach down in his pocket and see what it is?

>>210099
>>211060
I don't get the "what is the only word that is prohibited" part of this at all

>>211276
If you're making a riddle whose only answer is 'chess', you can describe the game in any which way you want, but you can't mention it's 'chess', because that wouldn't be a riddle anymore

It's like asking a question while giving the answer at the same time, you can't mention the answer inside your question because otherwise, your question wouldn't make sense

'What is the only word that is prohibited' basically is the answer to the question, in this case 'chess'

It's how i understood it anyway, but i see how it can seem confusing :/
