Evolution and Internet Sharing Sims / Survival of the flattest
« on: April 13, 2006, 08:56:01 PM »
Okay I will make it short because it is really late at my location...

I read something interesting on the net about the survival of the flattest, if that rings a bell.

My main concern on DB was always that highy fit hand written bots always did de-evolve into something less fit, and thereby the new less fit bot got the overhand in the sim and outcompeted the hand written bots, and in the end the end all bot became extinct. Which for me always seemed very strange. But some research in avida seems to indicate that this is possible when mutations rates are to high.

In short:
that low-performance individuals can outcompete high-performance individuals if they are more robust to mutations. Were robust means, that the DNA (code whatever) are more likely to get mutations which are not fitness decreasing.

Mmmhh, dont really know if we can but something like this onto DB. But somehow it seems to fit better into my DB view. I mean it is perfectly likely that the highly tuned hand written bot will continue to get degrading mutations, often because they have so much interaction between the genes and they are so compacted and structured vs. normal evolved bots, were the code often is in a messy state....

Just some random rabble... Hope I manage to get something meaning out of it.

Suggestions / No GUI
« on: April 12, 2006, 12:15:17 PM »
I just want to ask you if the final (oooohhh many lines of code to be written before that happens) C version, will include something similar to avida command line? I mean no GUI what so ever just the program running in the background dropping data files and saving once in a while. I am asking this, 'cous the GUI will get the program running much slower (and there is no idea in having a GUI if it should just run over night or something, you know, and so a lot of CPU cycles will be spared). I tried something like this in VB, but it is not really possible, or so I think.

Just some random thought again.

Okay I am not sure it was avida, maybe Tierra, doesnt matter really.

Suggestions / Regarding the enviroment grid!
« on: April 09, 2006, 04:00:21 PM »
Okay I have thought about the environment grid, and under all circumstances we need it.

What is the problem:
To CPU expensive, will slow down the simulation a lot! (Just to update others)

So what can we do? I have read on our wiki about this, and I recently had a course at uni, about OS' and Multiprogramming, so a simple idea started to form in my tiny head. In the VB version it will be nearly impossible to add threads (the timer being the best bet), but I the C version, it should be no problem, or so I think (but I do not known how we do it exactly). We could have a main thread with as it is now, and a secondary environment grid thread. Still this needs some more considerations, as is, but right now the C version is threaded, by the one main and the GUI.

Please correct me if I am wrong.

Biology / How does a cell reproduce!??
« on: October 12, 2005, 04:04:05 PM »
Just a simple question:

How does a cell/bacteria determine when to reproduce???

Is it determined by a gene or a few (or a million, doesnt matter) that:
"You now have one trillion energy/ATP, reproduce now!!!"
or
Is it a slow progress, were it creates the nessary enzymes all the time, and then a point with enough enzyme it splits into two?

or what???

Darwinbots Program Source Code / The FastInvSqrt function!
« on: October 02, 2005, 06:33:58 AM »
Although faster than normal squareroot functions (maybe haven't tested it)

But The FastInvSqrt has an error rate around 0.1 - 3 (and up) %!The error rate is based on how high x is is so FastInvSqrt(9)^-1 gives 0.3 %, while FastInvSqrt(2500)^-1 gives 8 %!!!!

I dont know if this matters difference from the real values matters.

Bugs and fixes / Bugs in NEW 2.4!
« on: October 02, 2005, 06:17:23 AM »
I cannot start a  simulation, without all the bots die in a flash of second...???
It seems no stable population can be reached... This is tested with different bots.

Off Topic / What is ASPCA?
« on: September 20, 2005, 03:41:52 PM »
In the Wiki, Intro, it states that if someone uses .pain, they will be prosecuted by the ASPCA.

What is ASPCA?

I know its a joke, but what does it mean?
