Simplest Evo Starter Bot

[Endy]

Yeah, the yellow shots are poison.

For some reason bots, even alga_minimalis, will occasionally gain poison; even though they're not coded to make it. Probably an obscure bug, doesn't seem to mess up attackers much so not too much of an issue.

Did you check the childrens' body levels? if these are too low they'll die rapidly.

[Testlund]

I got a weird veggie here. It swims round and round sideways over the screen. I'm not sure if this could be a bug or a genetic defect.

no, that looks capable.

I've been doing some 'ex nihlo' sims of my own in the new 2.42.3b

I started with a long string of zeros

After a much accelerated period of point mutation, I've got one that replicates:

Holy crap that is an intense genome

Nice work.  What sort of behavior is it exhibiting?  Controlled reproduction?  Is it a veg?

[Elite]

Unfortunately, it's cancerous. It just reproduces like mad
I tried to evolve it but it just lost it's ability to reproduce. If anyone else want's to try an evosim with it then go ahead.

I have no idea what else it could do, or why it's reproducing in the first place  

I'm just sort of experimenting with the new release  
I'm trying another accelerated ex nihlo evosim with a shorter genome at the moment

[Numsgil]

I think you'll need to see several abortive replicators before a good one develops.  Realistically I think you'd need to run a sim with medium mutation rates for ~10 Million cycles to see even a very, very basic bot develop.

[Elite]

I've been 'dissecting' the replicator that I evolved line by line

This is the self-replication code:

 start
 26 -10 -60 mult >> store

EDIT: I've highlighted the section it came from in my earlier post of the bot

[Elite]

I'm running a full Ex Nihlo sim now in 2.42.3

It's like Testlund's sim but without planet eaters, slightly smaller, and no costs

I've got a script to pause the sim as soon as a .repro command appears but I hope that as soon as one does it will start to evolve via natural selection and feed off the vegs.

Up to 200,000cy so far ...

 Yep that would do it:
 
 -10 * -60 = 600
 
 600 >> = 600 / 2 = 300 = .repro

[Elite]

Wow:

Code: [Select]

-6 .shoot store
 sqr -5 13 -2 << or
 -2 <
 16 | 1 sqr 16 -12 add
The first line looks a bit coherent. If it had a 'start' it would work, but unfortunately it doesn't

Nearly 500,000cy and counting ...

Two of my bots have managed to find a way to die, despite there not being any costs  
I suspect that they may have come too close to a bot that learned how to shoot

EDIT: Woo, 500,000 cycles

[Numsgil]

 Life will find a way
 
 I would make the bots as vegs, but give them 0 energy per turn.  Just have them repopulate when they die.  You'll never have to restart the simulation, and the bots still have an infinite supply of food if they ever learn to eat anything.

[Testlund]

The more zeros you have in the genome the greater the probability that a bot will eventually evolve to a functioning bot. I started a new evosim too with the 2.42.3a version. Been running it for 940000 cycles now. I don't use planet eaters this time because I want my veggies to be spread over the screen in case some bot develop the ability to feed. It seems that it's hardest to get a bot that can feed properly. Everyonce in awhile I get a bot that produces a little offspring, but it doesn't continue.

This time around I started with bots with only zeros like before but I gave the veggies a little more genes to work with.

My bot genes:

0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

My veggie genes:

cond
.nrg
0
0
start
0
0
0
0
0
0
stop
end

In 2.5 I have it so that negative shots are modded by 10.  That is, -11 = -1.

I also modded positive info shots by 1000.

The idea being that the shot type is sort of like a rotary bit changer, and if you rotate it too much you're rotated around in a complete circle.

Might be a good idea to add that to 2.4 as well.  Would definately make it more likely that a feeder would develop.

Evolution is terrible at finding one specific value if none of the other values are meaningful.

[Elite]

Damn, pressed the wrong button and overwrote my sim  

I think I'll run a really long one all today with the setting I saved
I'll use your suggestion to make the bots into vegs too

It's going much faster with no vegs
