Brainiac Stuff...

Brainiac Stuff.

Here's an impossible task. Youre supposed to draw a (single) line that crosses all the lines which connect two points (there's 16 of them), without crossing the same one twice.

I've been trying to solve this one for a loooooooong time - AND NOTHING!

So I thought that someone on this forum might have the answer.

[NAW/WAN]

Where did you get this from?

[Goat on Fire]

a friend told me. it's one of the most difficult ones of the logical problems. he also mentioned that the solution is kept in a museum, somewhere in england :-)

[Goat on Fire]

Oh, and one more thing. I've sent the same problem to a bunch of friends and they came up with an invalid solution.

here it is



the 'thread' has to CROSS THE LINE. It has to come in on one side and out on the other - NOT GO OVER IT. Just wanted to prevent any more peps from wasting time if I wasn't clear enough :-)

[Goat on Fire]

The same goes for this one.
it's not allowed to go along the line...

[Mr Karl]

I suppose you arnt allowed to cross the line you made?

[Goat on Fire]

I suppose you arnt allowed to cross the line you made?

no, that's not a problem. you just cant cross a line you aready did (excluding the one you are drawing)

[bre.star]

im stumped. this is the closest i got

[bre.star]

im stumped. this is the closest i got

nvm there are more than 16 places...im stumped i give up

[OliX]

I heard that this problem is impossible to solve

[purplepixie]

not sure I even understand the question

[Mr Karl]

ok so I'll try with crossing a line I made, otherwise I dont think this is possible

[MistressJennifer]

Too much for my blonde brain. Shellac me and put me in my chair...

[Goat on Fire]

nvm there are more than 16 places...im stumped i give up

AND

not sure I even understand the question.

ONCE AGAIN, (hopefully the last time). cross all the nubered "goals" ONCE (not twice+) with a single thread. It doesnt matter if you cross the thread 0 or 111 times. It's only important not to cross any of the numbered goals more and less than once. Do not go along the goal lines. Do not go through a dot which limits a goal.

Btw, where did you find more than 16 of them?




--------------------------------------------------------------------------

I heard that this problem is impossible to solve

Yes, that's what they say... And also that someone came up with the solution - and it's beeing kept in a museum - as a historica document. LOL.

I must be doing something wrong, because I did it and it seemed really easy. I don't know how to post, so if anyone wants the pic, just msg me.

... no, this can't be right.

You can post through remote servers (I use Tiny Pic). Just upload the image there and paste the image link.

You could be right... I think that this is just one of those problems that you solve on "BOOM". Either you know the answer from the first time you see it, or you wont get it no matter how long you try. Could be wrong though.

[purplepixie]

If it is impossible to solve then it wouldnt have been anywhere for goat on fire to find.........would it?

[Goat on Fire]

Only if I'm keeping it to myself :-) lyckily, i'm not a sadist

[Ouroboros]

Again, I'm not sure if I'm doing this right.

[ForrestBlack]

Here you go:

[Ouroboros]

Awesome.

[ForrestBlack]

...Do not go through a dot which limits a goal.

Oh, I see, issue a challenge and then change the rules, I see how this works...

[Venedotia]

LMFAO that's great!

[Goat on Fire]

Here you go:

No, that's as wrong as it gets

I love the colour though

To specify the stuff i did additionally would be like specifying that your RPG character with the Dexterity of 3, can't dodge arrows with with fingers. LOL.

---------------------

To Ouroboros:

I', not sure if you went along the middle line...

[Goat on Fire]

No, Ouroboros, I don't thik You got it right. Sorry.

----------------------------------------------------------------

To the others:

OK, now... This is my FINAL ATTEMPT ("Final Attempt" is a registered copyright of the "Try Again Corporation". Violators will endure consequences ), before I accept ForrestBlack's solution as the valid one (and only cause he has such a exquisite colour choice)



Connect the RED lines into a single thread.
Don't cross anything.
Just connect them.
That's what I was trying to explain all the time.

Same shit as before, except I hope I was more accurate this time :-)

(am I that confusing?)
Or, no wait, don't anwer that one. LOL.

[LrdSatanas]

ive tried for an hour always end up with 1 line un crossed you have same problem?

[mrs jones]

pretty sure this is mathematically impossible; someone who knows their geometry should write a proof. I think it has to do with the fact that there are 9 lines on the outside meaning to cross all of them you need to have one end start on the inside and the other on the outside, but with one end starting on the outside you can't cross all the inside lines

[Mr Karl]

been trying for a week almost think that its not possible , oh you cant cross your own line, it's possible too many ways then, it's in a museum in england you say?

Yes you CAN.

----------------------

That's what I've been told. You can look it up if you eer find out what's the name of the problem....

P.S. I've been trying for over an year now... giving up. trying again. giving up. trying again. etc...

[Mr Karl]

yeah your right you can cross a line it doesn't matter but after a lot of tries I think i'll leave this one for a while though

[-=Asmodeus=-]

DAMN YOU AND YOUR PUZZLE!!!
I have been in Microsoft Paint for 3 hours now playing with this damned puzzle.....
I have a test tommorow and what I am doing...Drawing Lines ....ARGHHH
I hope your happy

[ForrestBlack]

Your first set of rules were "Youre supposed to draw a (single) line that crosses all the lines which connect two points (there's 16 of them), without crossing the same one twice."

According to the challenge, I would say that my effort was not as wrong as it gets. According to the modified rules, yeah, sure, I accept that. On the otherhand, you said it was impossible, so I'm not sure what the motivation is to embark on a futile task. I'll just trust that you are honest in what you say. Why would you lie to us, right?

[OliX]

I think this is some serbian stuff again
making problems impossible to solve

[OliX]

meant to say:
*making problems that are impossible to solve*

[Raven]

I teach these things So i don't think it's very accurate if I help

[TheQuietPlace]

How about that? took me a couple minutes =D

[TheQuietPlace]

or...

[TheQuietPlace]

How about....

???
I've been working on this for like 10 minutes... 10 minutes will turn into just 5 more minutes... 5 more minutes will turn into "OH SHIT I GOTTA GET TO SCHOOL!"

[Morning Glory]

naw, cuz you can't cross the same line/ portal/goal thing twice. best i've been able to do was all but one line crossed.

[shev]

I joined the forum exclusively because I wanted to figure out an answer to this (I can't resist a good riddle), but maybe I'll fill a profile out later and come by after this too (unless I'm banned for posting URLs).

Three of the boxes have five lines one has to cross - these are labeled Five-Cross A through C. Two of the boxes have only four lines you have to cross, like a normal box. These are Four-Cross A and Four-Cross B.

Diagram of this at geocities[period]com[slash]shevtheprof[slash]diagrambox.jpg
(I couldn't write that out 'cause of rules.)

It's impossible to do this on a planar surface with a single thread if you leave the whole thing intact because of the five-cross boxes - they make a shape (the purplish lines) that requires the thread to make five crossings per box (an odd number) when the actual number of crosses allowed is only twelve (an even number). The riddle's tricky because it gives Four-Cross A and Four-Cross B as a distraction.

It IS possible to do this on a non-planar surface, though. ;D

Draw it on a donut instead:

geocities[period]com[slash]shevtheprof[slash]donutsolution[period]jpg

See how the lines are all drawn around the hole? Take advantage of that by drawing the thread AROUND the donut (it's behind the donut when the line is dotted) and it won't actually cross any lines twice since the thread is on the other side of our 3D torus. It gets where it needs to be, and no rules are broken... unlike my thing with the pictures before I'm allowed to post.
