The hunt for another B3457/S4568 ship

Post by Saka » March 11th, 2017, 4:05 am

B3457/S4568 is known for it's terribly slow c/5648, the slowest orthogonal elementary ship known. But are there other ships out there? Who knows? I have done ntzfind from p2 to p10, w6 to w8, currently doing p10 w7.

This is an outer-totalistic rule, so you can just use normal zfind. I hope that helps at the higher widths.

These types of rules interest me. I'm currently trying to hunt for the slowest ship by using blob rules. Wish me luck.

I find it interestingly coincidental that the speed of the spaceship is an anagram of the survival conditions.


Here's hoping for a c/7543 or c/8654 ship.

I strongly suggest a c/7 diagonal bilateral symmetric search, since we have this (promising) partial:

A really, really, really, really, really, really bad c/4 partial from zfind:

Code: Select all

x = 16, y = 8, rule = B3457/S4568
7b2o2$5b6o$3b10o$3b3ob2ob3o$b14o$3obobo2bobob3o$3ob8ob3o!
A considerably much better (but not as much as the one above) c/7:

Code: Select all

x = 18, y = 19, rule = B3457/S4568
8b2o2$6b6o2$4b2obo2bob2o$3bo10bo$2b3obo4bob3o$2bobo8bobo$2o2b10o2b2o$

Heres the final result, with 0 spaceships found:

Bump. I'm running qfind for c/9 orthogonal spaceships. There is no odd-symmetric ship at width 8, but the search reached a final depth of around 868. I'm currently doing even at the same width, which shows more promise so far.

EDIT: No c/9o on even. The final depth was around 2109.

Code: Select all

x = 4, y = 3, rule = B3-q4z5y/S234k5j

No c/3s at width 27, odd symmetric.
EDIT: No c/4s at width 27, odd symmetric.
EDIT 2: Spoke too soon, I should try all the other first rows first.

Edit 6: First rows for c/4o at width 27 that have been ruled out:

Code: Select all

?????????????o?????????????
????????????obo???????????? (We can assume b in the middle because o led to no results and we didn't specify any other cells.)
???????????obbbo??????????? (We know that the middle three are b because o led to no results and we didn't specify anything we didn't know for sure.)
I plan to keep eliminating outwards until I either eliminate the entire row, and therefore prove that there is no such spaceship, or until I find such a spaceship.
Edit 7: Currently searching this:

Code: Select all

??????????obbbbbo??????????
Edit 8: Moving on to the next front row.

Going through all of this will take a while. It takes JLS a few hours per search at this point.

You should use life_slice_ship_search for this, not JLS.

JLS is comparatively slower than LSSS and LSSS has infinite ship length, which allows us to know for sure that a ship really does not exist at a certain width and not just ridiculously long.

How do I tell it the first row so that I can rule out possibilities, moving towards the edges?
Edit: Fixed broken quote tag.
EDIT 2: I plan to finish through this search before starting one with LSSS. The screen is red because of night shift.

c/9o on even at width 9 returned negative, reaching a final depth of about 4700. Now trying odd...

Quick question, because I'm curious. I know that LSSS has infinite ship length for a reason, but what prevents the Gems analog of this kind of thing in Seeds from paralyzing the search?

Code: Select all

x = 5, y = 358, rule = B2/S

I'm not sure if it's safe to attempt width 10.

This is an outer-totalistic rule, so you can just use normal zfind. I hope that helps at the higher widths.
You claim that this would be less memory-intensive? Where would I find regular zfind?

Longest partial? Also, I highly recommend that you don't double-post. :P

ikpx2 should be worth trying, it was able to find spaceships in B3/S2, a difficult rule to find spaceships in (only one survival condition means extreme fragility), and I think it'll work here too, assuming you don't pass it through apgsearch.

That's kind of sad. What velocity do you plan to try next, assuming you decide to try another velocity?

EDIT: Tried a gfind search at width 14, c/5. No results for asymmetric or glide-reflective. No results for width-27 odd-symmetric, although that's due to a power outage, not an absence of shops. The maximum depth was somewhere around 490. The even-symmetric search was never reached.
