zerobot evolution

Numsgil:
It doesn't look like anything's really conditional except:

*.mysx 485 rnd store this stores non 0 values in to the first several sysvars depending on if it's moving sideways or not.

The other two I noticed:
.tie inc (forms ties) and 845 sqr >> >> dec (fire -1 shots) seem to always happen.

So, any summaries on how to get the best results for an evosim using a laptop with lowish performance and a problem with DB having an overflow error every hour or so?

I don't know, but I feel your pain, it really feels like something you want to just put on a spare pc and leave for a few days/weeks/months and come back to every so often to see how it’s getting on, but it doesn’t stay up and running for more than a day, sometimes only a few hours.
And on my last sim despite still having the option to ‘reset when all bots have died’ on, I came back to my pc to find it had crashed and the last 10 saves (30 mins apart) had no bots just veggies left.


--- Quote ---Initially the bots would tie everything to everything and proliferate in a section of the sim. Local availability of food would collapse and so would the bot population. Now bots are more mobile or maybe just less fixed, so the effect has lessened. As for interesting behaviour I am still looking for a moment to go and watch if tie forming is conditional or not. Having evolved from a zerobot the code is unreadable to me.

Heh, mine have done exactly the same, they just all tie-up in one big webbed swarming mass as they munch though a field of veggies and then when they are done, as they die back some break-away and scatter to find more food. A few come across a new patch and it starts over.  Without a large map with multiple veggie patches the population just spikes and then crashes down to extinction.

I am trying to get the veggies to disperse more into lots of smaller clumps to encourage a foraging behaviour instead of one big feeding frenzy then relying on numbers and random luck that one of them comes across a new patch. And I have the auto costs set to the slowest increment so it tries to provide a very small but gradual increase in pressure with emphases on things like tie cost.

Endy:
Normally I'll use a few zerobot veggies with point mutations set to 1 to rapidly generate the initial dna. After the useful dna builds up, I keep an eye out for any bots that develop shooting or feeding and then change point mutations to the default to make sure the trait doesn't go away.

I'll start them out as normal bots, with a few veggies providing nrg via sharenrg/ties and reproduction via memshots. Brownian motion is set to high and the sim is torroidal to help them initially find food. After awhile I'll reduce the amount of brownian motion and encourage the evolution of normal movement.

I've taken to using another bot to force the zerobots to produce "viruses" to duplicate useful dna. Have to be careful to avoid cross contamination, but it can considerably speed up evolution. I used it once with my own bot to duplicate it's movement dna, letting me ween them off sharefeeding. I used it again to mix one of Ikke's zerobot's reproductive dna and my zerobot's, letting them self reproduce.

Currently trying to slowly raise costs for them, they're operating under near F1 conditions with a veggie similar to Alga_Minimalis for food.

Not sure why you're getting overflow errors, haven't had any myself for awhile.

Are your bots actually moving by themselves? I've noticed alot of the bots tend to over-rely on ties and veggies for motion and don't go searching for food themselves.

Cyberduke:
Here is the error I am getting, sometimes the sim will run for days, other times only minutes, as in this case.

Also in my zerobot evo sim, all the graphs have stopped reporting on my bot? I have tried restarting the graphs, forking the species, saving and re starting the sim.
