Costs and energy usage.
Numsgil:
The default costs are quite arbitrary I imagine. Before my time as well. Usually when new features are added their costs are "defualted" to 0.
The only problem with the program as compared to real life is RAM. When certain DNA replicators learn to use viruses, like that short one Testlund evolved a while ago, DNA length starts to grow non stop.
This is exactly what real viruses are thought to do (hence the long portions of non coding, repeating patterns in many different genomes), so it's actually kind of cool. Unfortunately, RAM on the system eventually runs out, windows forces some of the program into virtual memory, and the whole program crawls to a standstill.
So I think it's wise to place at least a moderate cost on DNA length to prevent potentially megabytes of DNA data per bot, even if it's not necessarily mirrored in nature.
EricL:
FYI, there's a limit on DNA length of 32000 base pairs currently. Operations which try to take the DNA beyond this are prevented.
Testlund:
Ok, this is what I have come up with. Check the screenshot. 10% is going to basic and advanced commands, 10 % I imagine goes into the bot's body with that slider set to 10. 80% is divided into the fields wich you can see are not the default values. I've calculated the percentage for 1 energy point per cycle. Seem to work nice with Alga Minimalis, Animal Minimalis and R Fisannis. I start with 60 veggies and 30 bots. I have it set so there should be no costs applied if population goes below 30. I decided to not have any cost for dna upkeep this time until the dna gets too long.
If you have a better suggestion what values to set I whould like to know.
Numsgil:
What exactly happens when bots hit that 32000 wall? I think it mainly has to do with viruses and additive mutations. Does the virus just fizzle?
Testlund:
Are you asking me? I don't know. I don't think I got that far in that sim. I think the program will freeze LONG before then. Maybe I got to about 1000 dna length or so.
