Simulation Emporium / New zerobot simulation

« on: March 09, 2010, 12:03:26 PM »

OK, finally some news, we have reproduction going and the winner is zerobot with 900 zeroes! It was a bit surprise for me, because I beleived that first bots to reproduce will be ones with more zeroes or with random nubers...
Is this good time to introduce costs? There is over 400 zerobots with 900 zeroes in sim, other species are stuck below 10. Sim is draging like a dead cow by now, 1,6 cycles per sec.

OK just had two offspring, in simulation, of course   and parents are zorobots with lots of zeroes so it's 2:0:0, guys with random numbers didn't jutsify expectations so far, but it's only begining. Also bot's with only 900 zeroes are behind in evolution from their 3600 zeroes collegaues (as expected)... Bots with only 30 zeroes so far only evolved random moving (156 Mcycles).

The show goes on...

Suggestions / GPU acceleration + multithreading

« on: March 01, 2010, 03:39:46 AM »

The main limit at the moment for me is the lack of power I can throw into DB. I've got a dual core, and a decent nVidia gfx card...only one of which is at half load. With multithreading and gpu acceleration for the math functions you could massively increase the potential speed. It shouldn't be too great of a leap to code it in either, especially since you're building it from scratch again anyway.

There's post about using multicore processors

Bot Tavern / how to use multicore processors

« on: March 01, 2010, 03:32:23 AM »

I used that method when making evosims-it's great for those, but not particularly helpful outside that, as the teleporters tend to bottleneck the environments, so you end up with very little interaction.

Oh I remember now, it was You that first descireb this method, I appologize for stealing your idea

You are probably right, in my sim zerobots and bots with random numbers are mixed together, but so fan no strain has evolved reproduction, some bots from both sides evolved shooting and then lost that ability... Right now about 6Mcycles

Bot Tavern / how to use multicore processors

« on: February 28, 2010, 05:51:47 AM »

Ok, here is what I heard somewhere, tested it and it works. How to use multicore processors to speed up darwinbots. Don't know if it was written here, but maybe it's good to repeat  

In my case, I have dual core AMD turion processor. I started two simulations simultaneously. Then open task manager. Find processes Darwin 2.44.04.exe (depending on the version You are using, right click and click "set affinity" then You can assing each sim to one core. If You have more cores you can start more sims. You can connect them with teleporters to form one big sim and so on...    Hope that this will help a little...

When is good time to introduce costs? when reproduction starts? or feeding?

By the way I recommend using Ageing Costs together with Dynamic Costs otherwise there will be selective pressure for bots to do nothing.

You can set it to:

Age Cost: 0

Begins upon reaching: 0

Increase by: 0.000000001 (will be displayed as 1E-09)

I did this calculation for movement and rotation costs:

32000 / 24 / 60 /60 / 32 = 0.011574074074074074074074074074074 (1.157407E-02)

Hehe.  

Wow    respect man! How did ou do that???

Suggestions / day and night vision...

« on: February 25, 2010, 01:36:10 PM »

How vision affects to energy consumption? In real life vision is very energy demanding, so maybe bots with vision disabled will have advantage in lower energy needs.

Is it possible that during night period vision becames weaker? Like in real life, maybe we could develop new bot species that would "come out" only during the night. During daytime they would seek shelter from daytime species and vice versa...

I was wondwring when is good time to introduce costs. What is best cost settings to start with?

Bot Tavern / DNA lenght

« on: February 25, 2010, 09:05:09 AM »

There were some zerobot viruses that worked by incrementing random memory locations.  So I'd say the smallest complex DNA strand is something like:

1000 rnd inc

or maybe

1000 rnd dec

Or something like that.

¸
But is that real bot? I'm going for some interesting behavior like attacking target, runing away when attacked, feeding, reproducing and similar...

Bot Tavern / DNA lenght

« on: February 24, 2010, 02:49:46 PM »

Does anyone know what is the smallest lengh oft DNA that allows complex bot behavior?
I inserted 30 zerobots in sim, each 30 zeroes in DNA. I was thinking since most of zerobot DNA is junk DNA, and it's slowing computer down, maybe evolving bots with shorter DNA may speed up thinghs? Who knows, maybe bots with smaller starting DNA will have less junk, and more "useful" DNA?
I would like to hear your opinions...
Further info about sim expect in simulation emporium.

I made this. It generates lines of random numbers between 1 and 1,000. It asks you how many lines you want, 40 numbers on a line. I'm going to improve it to do both random numbers and dna commands like store, inc, add, etc. Sorry about its size, the program I made it in doesn't compile very well. Technically it doesn't complile at all, it just tokenizes it.

Great, thanx for the program :-)
Inserted 7 "zerobots" (can we still call them like that?) with random numbers...

Update on simulation: the shooting guy just lost it's ability for shooting so it's again 0:0

Just to mention, didn't know how to make random nubers sequence so I simply wrote sequence from 1-9 and then copy-paste it till I got 1234567891234567891234... hope that this still counts as random numbers zerobot? I posted dna for inspection.
