I like it!
Watching the two rakes interact, this pattern lets one of the rake's gliders reflect off the debris of the other.

TwinB7, I think you've made a really complex rake thingy as the bottom one shoots gliders to the right one, which makes the right one shoot gliders that don't collide with the bottom one's stream of gliders!! This is amazing!!

(Note: I found this manually accidentally when I was trying to copy, which instead I copied 3 of the same thing, which led me to experiment with these, and found this as the most interesting composition.)

TwinB7, here's a variation to your rle:

I like it! I wonder if the growth is more quadratic or linear? There are gliders in the square, but very sparsely, so who knows?
Running a 5,000 gen population plot (which took surprisingly long, and probably still isnt enough generations to get a good idea of the long run growth pattern) it seems linear, but with a lot of jagged spikes.

I don't know how to inert a picture without going to Photobucket and I'm far too lazy to do that, so why not supply it in .rle since that's what the output of the program is anyway:

TwinB7, do you think we can / I can (If you already did
) make it to be known in Golly or the whole internet?? I guess we'll see.

[phdanielli]

I mean we're like talking endless of good stuff that fascinates each other, I wonder what makes us work so well??

[twinb7]

Probably one of the reasons is that we're actually active on the forum ^^

[dvgrn]

I like it! I wonder if the growth is more quadratic or linear?

A few extra gliders won't push you over the line between linear and quadratic. Generally you need a structure that repeatedly generates growing objects. For non-engineered debris like this, switch engines are the most likely thing to show up.

In fact, I think they're still the only unbounded-population objects that have been seen emerging from random ash. No natural glider guns yet...!

Anyway, if you're interested in this kind of complex interaction between 90-degree puffers, Bill Gosper did a large number of experiments along these lines using an earlier version of Golly, several years ago now.

There's a link in the article to a semi-blog containing Nick Gotts' previous work at finding quadratic-growth interactions and other complex behavior, starting from small initial patterns. The blog is a little tricky to figure out (Nick says he hadn't figured out blogs himself yet, when he posted those patterns). The RLE for all the patterns is in the first-and-only posting, with occasional links to pictures in separate blogs with a few postings each.

[phdanielli]

Thanks, Dvrgn, but accidental discoveries won't ever be too useful. I'm just interested by how complex this thing can be and what potentials it can give.

[phdanielli]

@TwinB7's latest post up till this post.
Oh, I like the forums, it the only social media that I go to consistently.

[twinb7]

@Dvrgn:
I guess you're right, but it kinda feels like almost everything to be discovered in Life has been discovered. I have yet to find an automata that I can really sink my teeth into and break new ground...

[phdanielli]

@TwinB7's latest post:

Try digging in my "Virus" rule, may it ever surprise you as this rule is full of simple yet interesting stuff, yet discovered so recently by me.

[phdanielli]

This is so simple that I wonder why no one had discovered this yet, but anyways, I'm first!!

Code: Select all

x = 16, y = 15, rule = B3/S23

This line puffer / rake's width = a stellar 516!!
(I don't know if I should call it a puffer or a rake, also, is it linear growth or quadratic growth??)

This line puffer / rake's width = a stellar 516!!
(I don't know if I should call it a puffer or a rake, also, is it linear growth or quadratic growth??)

"Line puffer" is traditional. A (clean) rake is a puffer where all of the debris moves, and by default it has some kind of standard period. So even if you could figure out the period, this would be an extraordinarily dirty rake.

Looks like you've extended one of Tim Coe's superstable line puffers, and they've been found to grow quadratically almost without exception, I believe, if they're wide enough -- and this one is certainly ridiculously wide. The period grows exponentially with linear increases in width, and as soon as the period is big enough you usually start seeing occasional block-laying or glider-producing switch engines coming out of the ash.

I'm not sure if there's a more recent and complete list, but here are some old numbers on line-puffer periods, from Tim Coe in October 1995. This should give some sense of how big the period might be for this monster you've created:

This is so simple that I wonder why no one had discovered this yet, but anyways, I'm first!!

This is called Schick engine and it was discovered in 1972.

[phdanielli]

@Codeholic:

This isn't the shick engine, look closer!! It's a modification to it, that emits glider pairs + incomplete traffic lights!!

@Dvgrn:

If game of life was a war game, I would win as a team's engineer!!
This line puffer is just like a stellar sized smoke emitter that crashes ahead at half light speed!!

Are you positive the growth is quadratic? That doesn't make sense to me- it isn't filling a shape in two dimensions, so...?

Check the enclosed population plot. I'll do some statistical tests when it isn't three in the morning.

Are you positive the growth is quadratic? That doesn't make sense to me- it isn't filling a shape in two dimensions, so...?

Well, I'm not absolutely positive, no. I haven't run the puffer long enough to find the period, and then confirm that there's at least one switch engine produced in each cycle. Couldn't do that even if I wanted to: line puffer periods tend to be exponentially longer with linear increases in the width, so phdanielli's monstrosity will likely have such a high period that nobody will ever know what it is.

As a rough back-of-the-envelope calculation, based on Tim Coe's list, puffer periods seem to start regularly exceeding 10^N at a width of about 12(N-1). [Yes, I know, that's very rough...] So a width-518 line puffer will have a period maybe around 10^44.

Really big, in other words. Cosmic background radiation hasn't traveled that far since the Big Bang, even if you measure in nanometers.

So Hashlife is not going to be much help here. [For this kind of big chaotic pattern with not much repetition, Golly's QuickLife algorithm would generally be faster than Hashlife anyway, if you trimmed off the settled junk and extra gliders every now and then.]

But somewhere in all that 10^44 ticks of chaos, it's very very likely that a switch engine will be produced. Really that's an understatement -- it's very very likely that uncountable quintillions of switch engines will be produced in each cycle. But we only need one, repeated every 10^44 ticks, to get quadratic growth.

...I admit it's a very unsatisfactory kind of quadratic growth -- it wouldn't show up on population graphs until somewhere above T=10^100, I think, which might as well be never as far as we're concerned. But eventually the population increase from the ever-growing number of switch engines will inevitably outweigh the linear contribution from the line puffer.

In case all this theoretical hand-waving doesn't help, below is a less ridiculous version of a line puffer where you can actually watch the quadratic growth getting started -- though you'd still have to be pretty patient to see it showing up on a population graph.

Notice the rarer glider-producing switch engine that gets a start early on, around 634000 ticks. Not surprisingly, the resulting forward glider stream gets mixed up with the the backward glider stream from the line puffer, and the switch engine gets killed off by 760K ticks. Then the puffer goes periodic and starts making block-laying switch engines instead -- and those do survive, since they're slow enough that they never catch up with the glider streams from the puffer.

Here's some old line-puffer data from Tim Coe in May 1996, supporting the claim that switch engines are pretty much inevitable, as soon as you have a chaotic edge that's long enough. These are statistics from multiple shorter runs starting with random debris behind the engine; at these widths and lengths, a single symmetrical starting point would probably have started to cycle already.

This isn't the shick engine, look closer!! It's a modification to it, that emits glider pairs + incomplete traffic lights!!

So what? Why does it make it notable?

@Codeholic:

This makes a great difference as I found something new!! Not something already known!!

It depends how you define "new". The following pattern is also "new":

@Codeholic:

I didn't say that your pattern was "not new", besides, that phase was new, not the result itself, if you're talking like this, then basically, you're angering everyone in the world except John Conway because he's the one who "DISCOVERED" the rule B3/S23!!
