this is annoying puzzle, you can glue for hours
after 3 attempts i ended up with this :frown2: http://img32.imageshack.us/img32/9186/chessu.jpg
i have understood you need to go spiral around each step, but when i reach the end i miss something

You are doing better than me. I tried twice and left 13 and then 10. MM is quiet....maybe he will figure it out.Originally Posted by seniorita

Last night you had me laughing so hard - with the remarks about CoP , Egyptians jumping off their pyramids, many comments were hilarious.
That's very cool!

You win my admiration
But we have to consider - what if mm does it in 63 moves? What then?
Tell you what, if you can solve the puzzle (no cheatingI will send you something from USA. Maybe a hockey puck (or are they made in Canada
)
a8 (start) c7 d6 b8 d7 f8 h7 g5 h3 g1 e2 c1 a2 b4 c2 a1 b3 a5 b7 d8 f7 h8 g6 h4 g2 e1 f3 d2 b1 a3 b5 a7 c8 b6 a4 b2 d1 c3 d5 f4 h5 g3 h1 f2 d3 c5 e4 f6 g8 a6 g4 h2 f1 e3 c4 e5 c6 e7 f5 d4 e6 g7 e8 d6
(But I cheated, I know the trick.
Oh nonono mathman, delete this, I dont look, I m pretty stubborn, i want to solve this!!
but can you give a hint of your trick please, unless this horse secretely flies, I have tried all the possible spiral ways and I miss the corners at the end! I end up with 3 squares! :banging: Do you have to end up where you began, the secret?
My headchef is out of town, I have got the whole department playing with the damn horse today!
Janet did you find it?
I give up for today, I already feel enough stupid:boohoo: this horse turned out to be a lemon!
Mathman I read the essay you post, I miss something, but I want to see it again home, I havent done so theoritical analysis myself, most of the times i use theory to apply it in computer science, and mostly the differential sequences.
This problem is a special case of what is called a Hamiltonian path, or Hamiltonian circuit, in graph theory. It is used in serious applications like circuit design, transportation networks, and the like.
Here is the trick. At each move, go to the square that gives you the smallest number of possible plays on the next move. (If it is a tie, take either one. There are billions and billions of possible ways to do it in all.)
To see why this method works, consider your problem with missing the corners. Suppose your knight is at f7. Where should it go next? The move with the least number of next moves is to go into the corner, h8, right now, because after that there is only one possible move, g6.
If you don't go to the corner right now, you can never get there, because the only remaining square from which you can access h8 is g6, and then there is no way to get out again.
I have only tried it twice - late last night. It made my brain feel like an egg in a frying pan so I stopped.
I am still trying to figure out why the Egyptians built the pyramids? It was before cop - so what other reasons did they have? Maybe they thought it would scare away Alexander - or maybe they were hiding the fact that inside the pyramids were the world's first discos

And also music by the Bangles "Walk Like an Egyptian"
"If you're lookin' for all the CoP's their hangin' out in the donut shops....
Maybe you are toooo young to remember that song - I always loved that funny lyric about American Cops - and it is so true.
Did you ever see Steve Martin's SNL take on "King Tut" - hilarious.
I did find a great diagram of the Parthenon showing the Golden ratio last night. If I can find it again I will post the link. It shows how the Greeks also invented time travel, went to the future and fell in love with McDonalds hamburgers. They were so inspired by the "Golden Arches" that this led them to discovering the Golden Ratio. So the mighty Parthenon, most imitated architecture in history owes much to late 20th century Americans love of fast food.
i saw it now on youtube http://www.youtube.com/watch?v=pP7AJiQM2RI, i was not alive back then, was steve martin also a singer? he had a show, or what?It is fun!
are you on drugs?
I kid, that was funny
is all squares supposed to be covered or one is left open at the end?I did it with the tip thing twice, once you begin cautiously you get the point as it goes on without calculating moves but I ended up with one square, maybe it is because i get tired at the end and dont pay attention well.
anyway my boss wants to thank you for the productive chess hours the whole office has spent since yesterday

He has been the guest host of SNL more than any other. He has also starred in many movies (The Jerk, Roxanne, Father of the Bride and Shop Girl. He is also an author and he wrote "Shop Girl" and several other books. He also plays the banjo and loves music, especially "bluegrass" which is mountain music from Appalchian region of USA.
