A question about the age costs

(1/3) > >>

Testlund:
I'm wondering how the age costs work exactly. For example: I have a bot that is 131913 cycles old. I've been running this sim without any age costs selected, but for 3000 cycles ago I decided to put in some aging costs. I set the 'age cost to' 0.25 and 'Begin upon reaching' to 20000 cycles. Will this start counting from the moment I set it and click change in the GUI? If that's the case then this bot should start ageing at 148913 cycles. Also I'm wondering what will happen if I save and quit, and then load the sim again. Will the ageing continue to count where it left off or will it start from the beginning again? Also I'm wondering what the 'Increase cost log(age)' mean exactly. I presume it is some kind of acceleration on the cost value over time. If so, how much?  

Numsgil:
The start aging at X means the robot's age, not necessarily when you select the aging cost.

IE: set it to 20000 cycles and bots will begin aging when they are 20000 cycles old.

The increase cost log(age) does indeed indicate that the costs will increase as the bot ages.

More specific details I don't know.

Testlund:
I think that is a little strange, because I can't see my old bots get affected by age yet.

crank the cost up high and I bet you will.
it takes balancing the cost with a bots 'intake' of energy ...
you know, input/output ...
in the case of veggies, the nrg/cycle can't be too high, or you will never see
the age cost as it will be insignificant in comparison.
maybe Eric can give us some nominal starting numbers and explain
how they ramp up if using the log function.

Welwordion:
Actually this can be used quite interesting in Evo sims, make all bots vegs with around 3-11 nrg per cycle
then upon reaching a certain age make the nrg cost 4-11 (+1 to what you gain) so you have -1 netto that way
your bots wont die out and have enough energy to reproduce on the other hand methusalems that do not do anything will be killed and bots who learned to hunt will survive even after losing their veg bonus (this is also quite useful to limit the number of bots and to avoid Alzheimr as all bots can convert waste into energy).
