Artificial Life Experiments Show How Complex Functions Can Evolve

"Avida, is an artificial petri dish in which organisms not only reproduce, but also perform mathematical calculations to obtain rewards. Their reward is more computer time that they can use for making copies of themselves."

Artificial life in an artificially created environment with artificial intelligence endowed by its creator. Evolutionary?

[AndrewC]

In a million turn 10K pot.

ROFLMAO.

I'd hate to end-to-end test the darn thing for linearity.

[whattajoke]

Spoken like a "Constitutionalist(strict construction)that recognizes that inalienable rights come only from God and are reflected in Holy Scripture," as your profile says.

That noted, I must discount your opinions on evolutionary matters, sorry.

btw, what do you call the white cold frozen stuff that those so-called "snowmakers" at ski resorts make?

I've done a total of about 30 hours of electronics engineering in the last 30 years

Even so, you must know claims that a transistor "is in a sense two diodes tied back to back" clearly misses the mark and establishes the claimee as dabbling outside his field of expertise.

Buy a big bunch of 10K resistors and cull for one at that value.

Hint, control the temperature, as that will change the measured value.

Hint 2, use kelvin contacts (four leads - two to drive the test current, two to measure the voltage drop) to avoid contact resistance problems.

Or buy a 7K carbon resistor and a jeweler's file, measure the resistor and start filing a notch in it until the value rises to 9.4115K. Protect the cut with shellac or nail polish...

Computers are very good at iteration given a problem, a desired solution, a dbase and a good programmer.

Yup, and given a new not too hostile environment, a selection for better addapted members of a population, and a few ten's of thousands of generations, evolution/natural selection will result in a new species...

Or someone trying to explain it to a tyro...

[jwalsh07]

Does that mean that computers are good at iteration and evolution challenged?

[jwalsh07]

Or someone trying to explain it to a tyro...

Say what?

[AndrewC]

Hey, very good advice, except how long will it take to accomplish the task? I don't expect answer, because we all know it is not practical since it requires about a .005 per cent precision.

Buy a dictionary

Not to mention the precision of the temperature, humidity and pressure to maintain same. But hey, no biggie.

[null and void]

Does that mean that computers are good at iteration and evolution challenged?

No. It means computers can model reality. An iteration in a computer is a model of a generation in life.

[jwalsh07]

Buy a dictionary

Very neighborly of you.

[null and void]

With a bit of practice you could turn out one, maybe two a day...

[jwalsh07]

I looked up tyro and was flabbergasted.

The way to eduacte a novice is to present he or she with false information. Wonderful.

Do you teach in public schools?

[null and void]

Yup. Trying to teach you to fish, rather than giving you a sardine...

[null and void]

YOW!!! Good shot!

[jwalsh07]

An iteration in a computer is a model of a generation in life

:-} Really? What dictionary can I find that bit of wisdom in?

[Lurking Libertarian]

Sardine placemarker.
