The Hunt for a Tiny Diagonal Spaceship (Unsuccessful)

[biggiemac]

I'll give it some time this weekend. I think I can build from apgnano. Dare I expand the box of interest, perhaps to 37 cells?

I'll give it some time this weekend. I think I can build from apgnano. Dare I expand the box of interest, perhaps to 37 cells?

Of course! With apgnano's generation algorithm, that's probably not too much more CPU time than the current 33-cell search. But will you just have apgnano run each pattern to stabilization and then census the results? That makes a 37-cell enumeration look a little more ambitious, but still probably within reach I would guess.

I liked Alexey's implementation using ".field" files -- makes it trivial to add another cell or three, whenever the previous distributed search gets completed.

EDIT: Aha, the 132/256 search is complete. Turns out I guessed right, with a lot of help from Sokwe:

Code: Select all

x = 10, y = 10, rule = B3/S23
8bo$6b4o$4bob2obo$3b3o$2b3o3b2o$3bob2o$b2o2bo$b2o$2o2bo$b2obo!

I would guess that unless we filter them out with an apgsearch/apgnano hack, there will probably be hundreds of these kinds of oscillator results before the first spaceship is likely to show up. Probably mostly p10 like this one, though there are other combinations that CopperSearch doesn't forbid, like p12 or 24 -- pulsar plus something p4 or p8.

So: 130 through 132 have been checked now -- no results.

Is this a new oscillator? Probably not...

[Hdjensofjfnen]

Sorry if this is kinda short notice, but I'm currently searching #101.

[Hdjensofjfnen]

P.S. Can I minimize or close the window?

[Alexey_Nigin]

You can minimize it but not close.

[Kazyan]

#83 complete, with no results.

[fluffykitty]

Maybe 8478/16384? (Or 8477/16384.)

[skomick]

#5 complete, no results. I'll search #7, #8, #9, and #10.

[drc]

My searches are going to take a while. Sorry. My computer can only handle 500/s

[Hdjensofjfnen]

Searching #101 will be done over the weekend, I don't have access to my computer just now. I can't do it on my school's public computers...

[Hdjensofjfnen]

Can I put the computer to sleep while I'm doing it?

[dsmiller]

#98 complete with no results. Waiting for #99.

[Hdjensofjfnen]

I may possibly do it tonight.

[drc]

Can I put the computer to sleep while I'm doing it?

No, sadly

[Hdjensofjfnen]

More than 100 intact slots between 145 and 247...

[Hdjensofjfnen]

Can I put the computer to sleep while I'm doing it?

No, sadly

Dang it...

[Hdjensofjfnen]

Can I put the computer to sleep while I'm doing it?

No, sadly

This means I'll only be doing one, then.

#53 finished with no results:

Code: Select all

[i]CopperSearch version 0.2 ran with parameters 'd 53/256' and found the following patterns:[/i]

[i]Total: 0 patterns[/i]

EDIT: And so does #51:

Code: Select all

[i]CopperSearch version 0.2 ran with parameters 'd 51/256' and found the following patterns:[/i]

[i]Total: 0 patterns[/i]

EDIT: And even #54:

Code: Select all

[i]CopperSearch version 0.2 ran with parameters 'd 54/256' and found the following patterns:[/i]

[i]Total: 0 patterns[/i]

EDIT: At last, #52:

Code: Select all

[i]CopperSearch version 0.2 ran with parameters 'd 52/256' and found the following patterns:[/i]

[i]Total: 0 patterns[/i]

[drc]

Just finished 1/8th of both 144 and 248. Nothing.

[Bullet51]

I have added #171 and #172 to my search.

[Hdjensofjfnen]

So far, no result... yet.

[biggiemac]

68-71 finished with nothing to report.

[Alexey_Nigin]

For those who don't read the main CopperSearch thread: please upgrade to v0.3.

[Alexey_Nigin]

There seems to be an error with v0.3. Please wait until I sort it out.
