Title: Overflow
Post by: strangers on June 27, 2007, 12:31:23 AM

While running an evo sim with Animal Minimalis, after some 200k cycles I got an overflow error. I was running it with all the speed increasing things turned on.

I can't seem to reproduce the overflow.  A tip for when you start a new sim, set the user seed in random numbers under the general tab to any value.  That way the sim will (theoretically) be 100% reproducable.

Took me forever but I reproduced the overflow.  But I wasn't running it in VB so I have no idea what happened.  Try loading your error.sim into Darwinbots and seeing if it'll let you continue.  Mine does.  Seems to be some sort of phantom bug

Yeah, it let's me continue, so I just let it run for a few mintues then when I comeback it always shows an overflow error. It ussually happens anywhere between five and ten minutes.

Alot of the problem stems from the fact that 10 minutes in the program is something like 4 hours in VB.  But I'll see if I can start it up and let it run overnight to catch the problem.

I've used veggies storing rnd values in rnd locations and managed to catch a bunch of them.

Kind of funny actually, since the program is essentially de-bugging itself.
