shvarz:
I don't see any proof of that mutation rates don't work at all. I certainly see them working in every single sim I run. As for rates being defined in genes. That is a small sidestep and I can overlook that, especially because you can set the rate to be very low and use .mrepro when necessary to get high rates.
Botsareus:
Thats because I manualy set the best mutation rate (witch I got from the best bot from the run before) to all the new bots in the new run. It simply does not work , the not mutating virsions of the bot win. (yet again) Maybe the mutation rates are case specific and do not apply as "the best mutation rates for all bots".
Numsgil:
--- Quote ---Now to Nums question, how we model it. Same as I said before - have genes for digesting each food type (we should get three in v.3, right?). Use counters to up-regulate those that are used more frequently. Not a perfect solution, I can probably point out some weak points myself, but a step forward nevertheless.

More than three, I think we'll have close to 20 energy types in 3.0. Some organic, some inorganic. THen you can set what substances are available through the sim, so you can run general or very specific simulations.
The counter idea is pretty much what I'm thinking.
Each enzyme has something that counts how often it is used by things in the stomach. If something is using alot of one enzyme, the bot will produce more of that enzyme automatically.
However, on top of this autotomic system the DNA can override any of the default actions. So if you are smart enough to know that you'll be getting more of a certain substance soon, you can stimulate your stomach to produce more enzymes as if that substance were already in your stomach.
There are still a few issues to work out, but that's the basic system in a nutshell.
shvarz:
20 energy types?!?! When are we getting this, again? We wants it :boing: :boing: NOW :boing: :boing:

Earlier, Shvarz said
--- Quote ---Adult humans could not digest milk. Then they learned to grow cows and obtain milk from them. As a result, a mutation appeared that allowed adults to digest milk. Now it is present in majority of population and only some unfortunate people don't have it. Availability of food lead to appearance of enzymes.

This is what I have been saying. While it should be possible for some robots to eat most things, they should never be able to eat everything from the start.
New enzymes need to be available only by mutation.
I really don't like the idea that a robot could be able to produce ALL of the possible enzymes. That would put us right back where we are now. Everything would become a complete and utter omnivire.
