Thread For Your Useless Discoveries

Nothing in this universe is useless.
Have a good day!

Nope. I don't agree with you, Boka.

Yes, everything can be useful if you know how.
Have a good day!

So why do they throw methuselahs (<20000gens) into the rules?

So why do they throw methuselahs (<20000gens) into the rules?

At one time, methuselahs that ran for 20000 generations were the state of the art. As time progressed, and apgsearch was set up to recognize methuselahs, and new methuselahs with longer periods started being found, ones with lower periods became less and less interesting. However "interesting" is typically a very subjective quality that is best left to human filtering, rather letting machines do it.

Yep. Dean Hickerson stated that this pattern is an interesting methuselah:

Code: Select all

x = 20, y = 23, rule = B3/S23

but it is obviously not.

1. You are contradicting yourself. You said, for example, that the B34c/S23 c/7 is completely useless and we should not synthesis it etc.
2. At some point of view, everything in the CGoL universe is useless.
3. I still don't see how "everything can be useful if you know how". That sounds like "there is actually a p19 oscillator/a c/18 spaceship, the empty space".

@ Hunting

I was "hunting" your last post

so I could wish you

Happy Birthday !

this is an interesting thread

one may never know when something might come in handy

that which was useless yesterday

may become indispensable tomorrow

in CGoL many are "expert" in the ASH ( still-life, oscillators, space-ships and higher-ordered constructs made-up of these )

but I have always felt that the "real show" is the FIRE and so spend much of my time in CGoL watching the fires burning...

re-visiting this pattern from your post above :

EDIT ( persists 18,692gens and emits 43 Gliders )

Code: Select all

x = 20, y = 23, rule = B3/S23
10bo$9bobo5bo$9b2o6b2o3$bo$3o16bo$7b2o6bo2bo$8bo6b3o8$5b2o3b3o$4b2o4bo
2bo$4bo5bo3bo$14bo$10bo3bo$10bo2bo$10b3o!

I do not know why Dean Hickerson thought that it was interesting - but DH had a lot of collections of interesting stuff -

I find that pattern interesting because of the way the firecloud "reburns"; that is to say, re-kindling its own debris/ash;

indeed, the fire extinguishes only after it definitively leaves the main debris field. This fire, like so many others, seems

to contain the seed of a periodic pattern that is begging to be isolated and stabilized - and we will never know it until

someone does - and I used to collect interesting fires like these but ran out of time - "One man's trash is another man's

TREASURE" !

Happy Birthday !

Funny- I remember seeing that pattern when I was a novice and commenting on it
Come to think of it, it would be pretty cool if we could extend it

it seems to want to be extended vertically with pairs of blocks :

Incidentally, I think that large eater on the top is the first method of cleanly deleting the TL predecessor (or block, depending on an extra eater placement) that would otherwise form from this factory. I think that part goes in a different thread.

A custom Corderpuffer releasing Herschels on one side could certainly be engineered, but without a lot of search time they'd probably be fairly big and awkward. Might not happen unless someone comes up with an actual good use for those output Herschels.

A sacrificial block in the path of a canada goose can release the glider and produce and unworkable mess: ...

It's quite likely that many spaceships that have tag-alongs (whether true ones like the Canada Goose, or fake ones like the Fireship that actually alter the ship itself), may have ways to remove the tag-alongs and allow the ship itself to cleanly escape. This could be done with a judicious arrangement of still-lifes if the tag-along is wider than the ship itself. This is probably more likely to work with glider tag-alongs, as the coupling mechanism between the glider and the tag-along is usually extremely fragile, and most such tag-alongs are fairly wide.
