Давай подождем чуть-чуть. MetaDriver хотел парочку решений найти, зачем кайф человеку обламывать :).

I wanted to, too. And then we'll talk about who was looking.

Аналитическое, возможно, будет, но вряд ли будет охватывать все решения. Да такая задача вроде и не ставилась. Тут бы одно найти, а найдено уже несколько.

sanyooooook, ты нашел много решений - или 3 года искал хотя бы одно?

I was looking for at least one

Lana...! :) I sat for another hour trying unsuccessfully to cross two hedgehogs. I can't go any further. Just give me the whole list, please.

I took a good look at your solution. I'm convinced it satisfies the odds-and-odds arrangement I found yesterday. I'll be satisfied with that. :)

One more interesting thing: judging from the condition in your program, in fact there should be twelve solutions - one 180 turn in the condition is admissible (around edge "12").

 

Andrei TheXpert once gave a link to a game

Not an intrusive brain fitness game.

 
You'll have to put it out there. And tell me how you made the decisions.

Все верно поняли. я как человек высшей математике не обучавшийся пошел влоб.

26 минут Атом330 считал.

if (($a1+$a2 == 12) &&
($a3+$a4 == 12) &&
(($a9+$a5 == $a1) ||($a9+$a1 == $a5) || ($a1+$a5==$a9)) &&
(($a11+$a6 == $a2) ||($a11+$a2 == $a6) || ($a2+$a6==$a11)) &&
(($a9+$a7 == $a3) ||($a9+$a3 == $a7) || ($a3+$a7==$a9)) &&
(($a11+$a8 == $a4) ||($a11+$a4 == $a8) || ($a4+$a8==$a11)) &&
(($a7+$a8 == $a10) ||($a7+$a10 == $a8) || ($a8+$a10==$a7)) &&
(($a5+$a6 == $a10) ||($a5+$a10 == $a6) || ($a10+$a6==$a5)) ){
print "$a1,$a2,$a3,$a4,$a5,$a6,$a7,$a8,$a9,$a10,$a11\n";
}


Это условие, остальное перебором.


He's already said it's a 26-minute trial.

 

a1 .. a11. a12 is accepted everywhere as 12 for peace of mind.

By the way, it is possible that if you name the ribs in the right order, the mirroring might show up. At least I expected to see it, but didn't.
