The way we did this in the MC simulations of magnets was to "renormalize" the lattice using "block spins." A block spin is the net result of adding up all of the elements in (for instance) a 3x3 block. It works for this lattice too, just using B and W, and the result just being B or W. Just c

this is very interesting. Can you compute some properties, like the distribution of cluster sizes, or diagrams for cluster size / boundary size pairs? I don't know much about fractals, but does this picture have some fractal properties, too? Here's some numbers (on a torus board) : BoardSize, B

here's my first guess at don's question about how this would affect the game. my intuition is weak here, but i'll take a stab at it just for fun. no edges, no corners and no center mean that you're effectively playing in the "middle" at all times. this should mean that life would be harder to mak

But is it still a good game? I wasn't asking if it's different, that is obviously true. I can imagine it would be a more difficult game - no safety in corners, no base to build from.But does this make the game more trivial, simple or ruin it in some way? - Don On Tue, 2007-02-20 at 10:0
