This is a diffusion simulator.  It explains the math.  Partial derivatives.   :puke:

Hehe, I love that smiley.

It's shockwave, so you of course need shockwave on your computer.

Or do you mean my smiley?   :puke:

But did it tell about the math?

See, I got about halfway through that page before I even saw it just thinking on my own.  Forgot you can use taylor polynomial for multivariable function.

No matter how we do it, this is going to be a huge hit on speed.  Diffusion is a major, major issue.  So much so I've considered at times not letting things diffuse at all.

I can't know for sure till I actually have code that does it, but the one psuedo-egrid PY made a while ago wasn't all that good at diffusing...  It only did it every like 10 cycles or whatever, otherwise it was too slow.

Then why the Hell didn't you post a linky?   :lol:

Better not to let it diffuse... we are hitting the head again on O(n^2)!

Shack method?

Without diffusing, we don't get bots being able to communicate over areas using pheremones.  Which is a big part of alot of life.

That might be a necessary thing we don't get to play with if the computations get too CPU expensive though.

how about a simple routine that just randomly chooses a few grid locations (maybe 100) per cycle and moves stuff into neighboring grid locations.

That way we get difusion without too much slowdown
