CODE

Wolves versus Sheep -- the eternal struggle continues. This code attempts to generate a square in which a given number of wolves are unable to attack a given number of sheep. For example:

S S . . .     |  wvs -b 5 -s 3 -w 5
. . . W W     |
. . . . W     |
S . . . .     |
. . W W .     |
--------------+--------------------
S . S S . .   |  wvs -b 6 -s 5 -w 6
. . . . . W   |
S . S . . .   |
. . . . W .   |
. W . . . W   |
. W . . W .   |
--------------+--------------------
S . .         |  wvs -b 3 -s 1 -w 2
. . W         |
. W .         |
--------------+--------------------
Can't do it.  |  wvs -b 3 -s 2 -w 2

Here's a bit of geeky code which attempts to generate a 6x6 Euler square. Damn it, if I can't take the time to find a proof that no such square exists, I'll exhaustively prove it to myself through brute force.
