Comment on Wa-Tor: An Ecosimulation by ~DovSherman[top] [parent]

Slightly mixed up. Granted, I only know of anti-matter from school (my senior year high school teacher to be precise) and some independent study, but first there is a certain particle which can only travel faster than the speed of light and cannot slow down below the lightspeed barrier. This particle, like every other has its anti-matter particle. The theory is that matter came out of a vacuum which was the universe, as a result there was a hole in the universe and this hole is anti-matter. Anti-matter looks and acts exactly like actual matter (it has been seen and collected, but it is destroyed as soon as it comes into contact with a particle or matter), the only noted difference so far is that it usually has a reversed polarity (although this does not hold true for particles which are found with both or no polarity). I have heard there is a way to tell whether one is seeing matter or anti-matter, but I don't know what it is and I think this assumes that we are made of matter anyway when it is quite possible that we are composed of anti-matter (we are nothing more than holes in the universe). Also, once anti-matter is produced it can be held in place by strong magnetic forces (which i have heard of an experiment where a fairly large quantity of anti-particles were held in place and shot out in a beam at a group of matter within this controlled area, about the only thing that can be done with it).

This is so simple, yet insanely entertaining.

This is seriously cool. Its was great to watch the populations fluxuate in patterns. Patterns that grow so extreme that is results in the extinction of one species, in the case I watched, it was the sharks. Really cool simulation.

The way I have it, when the sharks go extinct, the simulation immediately stops. If the fish go extinct, it keeps going. Of course, if the fish go extinct, the sharks will soon follow since they'll have nothing to eat. But if the sharks all go extinct without killing off all the fish first, if the simulation didn't stop, the fish would simply grow and grow until the fill the world with no more room to move.

Makes sense. Really well thought out, what was your inspiration to do a flash project like this?

I was just browsing a book on my shelf and thought it might be fun to try putting some of the experiments described into a Flash format. The book, "Armchair Universe" by A. K. Dewdney, is a collection of articles, many of which were previously published in the Computer Recreations section of Scientific American. There's a lot of nifty stuff in there like perceptrons, tesseracts, fractals, life, facebender, and so on. I'd also recommend Dewdney's "Magic Machine" and "The New Turing Omnibus" which have an even greater variety of interesting computer experiments.

This assumes that sharks eat as much as they possibly can, that if the resources are available they will eat every move. Anyway, that makes the system easy to manipulate. A single shark is placed in apopulation of 50 fish, it breeds every seven moves while fish breed after every 1 move. The shark starves unless it eats within 1 move. (Default size.) The population is self sustaining if it starts off well, but it moves so erratically (it either can't be real or is all too real). Anyway, the system just seems so easy to manipulate. With quick-breeding fish and quick-starving sharks its almost guaranteed to succeed.

Those books sound interesting. I have a few questions. 1) Does the "Armchair Universe" book include infinite regression? A common example, in case you're not sure, is place two mirrors parallel and facing each other, and if you look in either mirror, you can see reflected in it what looks like an unlimited number of mirrors. There was an article on that in S.A. a while ago, and had a neat infinite regression of the S.A. cover picture on the cover.

2) Is tesseract the same concept as how the characters in A Wrinkle in Time use to travel?

3) I've never heard of perceptrons, and I'm not sure what facebender is. Can you give me a quick description of each?

4) I've also been trying to find out about antimatter. I know it's the opposite of matter, but can you tell me if it actually exists, and if so, where (is it everywhere or not on Earth), and what might it look like?

I also have a question about the 4-D hypercube you uploaded. Isn't the fourth dimension time? How do you draw a shape that represents that?

Thanks, Dov(e), for your time, and you have some interesting posts this time around!

That's a good point. But finding the "right" parameters doesn't necessarily mean simply providing a very long-running ecosystem. It means finding providing both a long-term ecosystem AND one in which behavior is plausible.

I find that some good parameters would have the fish to breed very quickly and that sharks should starve at a slower rate than fish breed but not too much so. Shark breeding should be around 3 times as slow as shark starvation. Of course, that's just one variation on the parameters and the shape of the environment (small, huge square, long-thin rectangle) can have a big effect as well.
