Thanks for setting me straight, Dan. I guess my proposed discretization is pretty trivial. I'm surprised no one has done a simulation of David's original model. Are there no coding-addicts among us craving a quick Coder's High? Jim P.S. David, can you tell us anything about the genesis of your question? On 6/7/12, Dan Asimov <dasimov@earthlink.net> wrote:
What happens here seems very clear after drawing one time-vs.-distance plot for each bullet on the tx-plane -- assuming one bullet per second.
* Each speed-2 bullet annihilates the most recent speed-1 bullet after 1 second.
Unless of course the speed-2 bullet is the first one, in which case it goes
forever in a straight line.

<< . . . I'd also like to see what happens with a non-random gun that simply alternates between emitting speed-1 bullets and speed-2 bullets; probably it gives something with a simple fractal structure, but I'm too tired right now to do by-hand simulations or to code. . . .
