Darwinbots3 / Re: Boolean memory

« on: January 29, 2012, 04:26:38 AM »

I remember learning this at Delft university. This has confronted me with the knowledge that I can no longer reproduce this on my own. Knowledge has a half life...

A maximium number of bots is already in there somewhere.. What is the added value of your proposal?

Just out of curiosity, how much time do you spend on DB3?

Suggestions / plants herbivores and carnivores

« on: November 30, 2011, 03:22:24 AM »

I was just thinking about some comment surrounding the implementation of .chloro and came up with a suggestion. Implement a digestive track in DB to create the distinction between herbivores and carnivores. The mechanism should be something as follows:
both .chloro and .body translate into mass, inertia and energy consumption when moving
eating is absorbing .chloro or .body into the gut, adding mass to the predator
absorbed .chloro and .body have have a rate of digestion which differs and is dependent on predator size (body is digested twice as fast as chloro, both are digested proportionally to predator mass)
absorbed .chloro and .body each have their own conversion rate into energy (1 body gives 10 times the amount of energy 1 chloro does)
With these rules we should be able to build a food chain in db.

Download a bot and watch it evolve. No programming skill required

Evolution and Internet Sharing Sims / Re: Internet Mode Ex Nihilo Sim

That would be possible, it would just require a lot of work!

Not at all, some memory, a form and a check.
Building the sim is user preference, once made (F3 etc) a template.

I once proposed to have an on / off switch for each command, allowing full controll of a sim.

Right now IM works just by dumping files onto FTP, so the primary weak point for contamination is actually the server.
...
Of course, it'd still just be a matter of time until someone griefed it just for the hell of it.  But it would probably last for months or years.

Don't kid yourself. Contamination will be no exception if there are no barriers. Suppose I'm a newbie exploring DB. I start a sim, click left & right to see what happens, press link to IM and presto a minimalis released.
If you attach userID of the owner of the sim to all bots created in that sim and their descendants you'd have an option to track (which is fun in its own right) and kill (as admin)

no the values on the stack stay there until removed by clearbool(clears the entire boolean stack) or dropbool (removes the first from the stack)

Untagged bots / Re: Chariotbot

The issue is not computer power. The issue is having someone both willing and able to run a league. DIY is the best option in this respect. Posting a bot and hoping someone else will do it for you doesn't get the job done as often...

Bot Challenges / Re: Shortest Fully Functional Bot

« on: May 05, 2011, 09:37:26 AM »

How can we stimulate DNA shortening trought evolution? I found settings "DNA upkeep cost". What is that mean?

cost per turn per bp. Increase this and likelihood of deletions and shorter bots will evolve. This is not hard
Evolving a shorter "fully functional" bot is harder. If the cost of loosing a function is smaller than the gain of a shorter genome energy is gained and the functions will be lost. Evolution is lazy..
