What has a binary operation, an identity element, the inverse property, but only has associativity during the full moon?

Question: what happens if you fall over? You've lost gravitational potential energy, so where does it go? Heat. If you had some way to eject heat (as black body infrared realisation) in a particular direction, you could use that, but that may be forbidden by the "you can't eject anything"...

Given this puzzle dates from 1850, I assumed it had been posted here before, but I wouldn't know what to search for, and nothing I tried found it. If someone knows it is here and can link it, please lock this thread. Fifteen young ladies in a school walk out three abreast for seven days in successio...

The wikipedia article mentions a random algorithm that runs in 1.657^n: https://en.wikipedia.org/wiki/Hamiltonian_path_problem

Pretty sure that's somewhat faster than the algorithm you sketch (which, in the form of the Held-Karp algorithm, is also mentioned in the same article).

quintopia

thanks that's the one.

Looking for a board game. Competitive. Goal is to colonize mars, which is divided into regions named after Sci-Fi authors. It's a dice work-replacement game, where the dice are your ships. Can't seem to Google it.

quintopia

Yep, Cauchy nailed it. I forgot to consider inferences one could make based on the "can't repeat, so remaining rooms are contiguous" condition.

(1) I would not play the game at all, because gambling is immoral. "Well, here in the future, we've perfected the art of machines that print food from raw organic materials. Unfortunately, due to war and sanctions on our country, in addition to our burgeoning population, we don't have enough r...

That 31 moves is a lower bound is obvious, or in the nxn case, that (n-1)*n+1 is a lower bound. Basically, visiting every position on five of the rows before ever setting foot in the sixth row makes it impossible to determine what row he is on until that last move. I'm fairly confident ...

quintopia

I definitively wouldn't be confident enough for that. I wouldn't be either. Yes, I meant to say "likely." In which case, I disagree. From what I've seen, people are more likely to overestimate small probabilities than underestimate large ones. People who play the lottery for instance. The...

I disagree. In blue eyes, if the Guru says they see someone with blue eyes, and you don't see anybody else with blue eyes, you should be absolutely certain that your eyes are blue and that it's the reason the Guru said that, to know your eyes are blue. Otherwise, you just scratch your head, and thi...

quintopia

They're absolutely certain that the Guru is telling the truth and that if there was a single person with blue eyes, they're absolutely certain that it would leave the island the first day. Absolute certainty is not a prerequisite for blue eyes. In fact, at no point does it refer to absolute certain...

quintopia

In the puzzle's world, no outcome from the coin should affect your certainty, because if it did then you weren't certain to begin with. People reject "You know for certain that the coin is biased in your favor: 70 to 30" from the puzzle, and go "no, I don't know for certain". Ex...

quintopia

It's not the number of losses in a row that I can't comprehend. That the coin comes up tails that many times is easy to imagine. No harder than omniscient gods that always tell the truth anyway. What is literally incomprehensible is the idea of knowing something with absolute certainty. It is litera...

It's more than just having to accept an implausible/impossible hypothetical. It's having to accept a hypothetical that is not even possible to imagine because it makes no sense. . It's like trying to imagine a hill of beans with infinitely many beans in it, and then being asked what one would do wit...

quintopia

I reject the hypothetical. I refuse to be absolutely certain about anything. How would I even come to absolute certainty? Certainly not empirically. Could someone just tell me and I would believe them? No, because I would I ever come to absolute trust in them? Certainly not empirically. Being absolu...

Wandboy is infinitely less funny than 'Ceramic Harold'. Personally, I've always called him "Woolly Tinker". His best friend is Donald Ferrety. And they were friends with Mercurina McMaster-Carr. Interesting. My sister dates a McMaster-Carr employee, but this is the first I'd heard of thei...

In contrast, "When Will My Life Begin?" , "Mother Knows Best", and "I see the light" from Tangled all are similar musically and unify into a single theme. Donna Murphy and Mandy Moore may not have the same legendary status as Julie Andrews, but they carry the movie qui...

Now that the wild 2048 craze has passed and only the original remains complex and deep enough to hold anyone's attention, let's talk about Threes. Does anyone here play? What are your high scores? What are some strategies I could use to get higher than the 768 vampire?

Nice try. But you have to go deeper to get out!

Granted. State education lotteries go completely unfunded, and schools are forced to shed special education and arts programs to stay afloat. Which is fine since children are no longer fooled into believing their educations are useful or meaningful. Dad jokes become impossible. I wish the next poste...

You try to get a grip on the necktie, but as soon as you start pulling in it, the brass bar it hangs from flexes slightly. The east wall rotates to reveal a staircase up to the second floor!
