A mathematician is in Africa trying to capture a lion. When he spots one he proceeds to build a fence around himself and says, "I define this to be outside!"

And we're proud of our captures!

There's a mathematical technique called 'lion-hunting' which goes like this: the hunter divides the world in two, and decides which side the lion is on. He then divides that half in two and continues for all eternity. As a result, the lion is contained in an arbitrarily small cage.
Originally posted by chasparosIsn't there a physics riddle dealing with Quantum Mechanics called "Schrodingers Cat" where using the probalistic nature of QM you don't know if the cat is dead or alive or both? Or something like that.....this is so off-topic, but I couldn't resist.

Once the cage is smaller than the lion, You start running into
problems. in which part of this cage is the lion? Is it in both?
Is i more in one than the other?

Colin, can you solve the following related problem?
The Wolfpack are wandering around on some simply connected subset of the Earth's surface. Members of the Wolfpack can also be members of the Culture of Death and the Stand-Up Comedians, but don't need to be. Now, Ivanhoe is designing enclosures for the Wolves so that they don't start having fun ...[text shortened]... s takes place on a plane or some other surface? What if the surface is not orientable?
Originally posted by chasparosI was unclear. I do mean that neighboring areas may not contain wolves of the same type. I am asking for a general classification of which fence-configurations can accomplish this and which can't, rather than a particular method, althoug yours is valid.
If by "next to" you mean: Neighboring areas may not contain wolf of
same type.
Then start building a fence on the edge.. Build it in a loop. Place any wolf in the containment created. go straight. build another loop not intersecting or tangenting any other previously constructed loop(Insufficient english vocabulary) aso.
However if by "next to" yo ...[text shortened]... olf of the other type. Build parallell fences in straight lines. Place wolves
CoD,SUC,CoD,SUC.
Originally posted by royalchickenYes I was being a bit simplistic.

Well, remember how many sorts of wolf you have.
Originally posted by iamatigerOh, my bad. Under my rules, everything's pretty much equivalent to a chessboard, so you're right.

Given your fence laying rules, I'm not sure that it is possible to construct a division which can't be coloured like that.
