Puzzles
Four Men Crossing a Bridge:
There are four men who would all like to cross a rickety old bridge. (Perhaps it is more accurate to say that they'd like to get to the other side.) The old bridge will only support 2 men at a time, and it is night time, so every crossing must use the one flashlight that they all share. The four men each have different walking speeds; the fastest each of them can cross is 1 minute, 2 minutes, 5, minutes, and 10 minutes. If they pair up, since they must share the flashlight, they can only cross in the time that it would take the slower of the two. Given that the shortest time to get them all across is 17 minutes total, how should they all cross?

Re: Puzzles
Two points:
First, this problem is already on the site at http://www.flooble.com/perplexus/show.php?pid=10
Second the proper way to submit a problem is through the "Submit a problem link" just under the Log In/Log Out button. Your problem will not show up immediately, as only one new problem a day is released and there is currently a backlog of 24 problems, but unless it is rejected (usually because it duplicates an earlier problem, as this one does  and you will be notified if that's the case), it will turn up in a couple of weeks.

Re: Puzzles
TomM's absolutely right. I ask people not to post problems in the forums, since here they won't be read by as many people, and won't have the chance to be featured as the "Latest" problem. (Which would be a great shame if it was a good puzzle.)
In addition, I think you will agree that the design of perplexus' main is pretty well suited for posting and discussing problems: the user's comments are not shown all at once, and neither is the solution  this gives our visitors a chance to think about it on their own, but also get help if they can't solve the problem. Plus comments allow you to indicate the level of "spoilage".
Perhaps I should make this thread "sticky"... But that would require implementing stickyness :)

Re: Puzzles
What you can't do is get other people to read and/or discuss your puzzles after you submit them to the wrong place.

Re: Puzzles
I didn't say you couldn't. It's just that you won't get much of an audience for it. The Submit a Puzzle link on the front page is a much better place.

A is a liar and B is a knight
Ravi,why do you say my puzzle is impossible?
The answer is that A is a liar and B is a knight.

Re: Puzzles
If A is a liar then when he says that both himself and B is a liar then he is speaking the truth (unless you consider the two together), or else if seen individually, we see that A though being a Liar, is speaking the truth.
And yes I'll surely make the tenth one. :)

Re: Puzzles
Tim you had asked me the question where A says, "At least one of A and B is a Liar".
This is possible for three cases:
(1) A: Knight, B: Knight
(2) A: Liar, B: Liar
(3) A: Knight, B: Liar
Isn't this correct Tim ?

A is a knight and B is a liar
Actually,(3) is the one and only way it can be possible.
It is only possible if A is a knight and B is a liar.
If A is a liar,then there would be at least one liar,and A,being a liar,would not have told the truth.
Therefore,A is a knight,so there really is at least one liar,but A is not a liar,so the liar is B.

Re: Puzzles
And another reason (as I learned with one of my problems) is the "common" 100 or so puzzles are already on the site. Submitting the problem helps filter out some of the repeat problems.
I like your guessme and other puzzles, so do create others!

Re: Puzzles
Actually Gamer those problems (Riddles) had been all given the same subject Guess What/Who and that is why Levik changed the first few to Guessme One, Two, Three and so later when I posted more riddles, I myself gave the subject's names as Guessme Four, Five, Six, ....and so on. But now you will find the riddles submitted by me (though less in number compared to the ones posted before) have a different subject, that is, other than Guessme Ten, Eleven,....and so on.
And yes Gamer I have posted a few more riddles but with a different subject. But if you people like that kind of a subject (I mean Guessme 1, Guessme 2, Guessme 3, Guessme 4,....,etc.), then I'll change the subjects of the other riddles that I have submitted.
Please do reply to this one stating whether I should change the subject or not.
Thank You.

Re: Puzzles
I think subjects like Yes, Sir are, in my opinion, good as they are. :)
I have only been around for a month or so (my first problem is on the site), so I haven't seen some of the old items on the site.
