Another issue is that, as far as I can tell, there's no set end date for voting. Unlike with nominations, I believe there should be a specific date and time when voting should end. The voting period needs to be long enough that infrequent visitors have a chance to vote. Back to my earlier point: alt...

Waiting is fine. (Starting it at exactly midnight UTC would be nice too.) I was waiting for a moderator to approve the descriptions based on this sentence: We want to come to a consensus on the finalized list before we start the voting thread. However, since that apparently isn't necessary, I'll st...

How did you find that? I found the small 2c/6 tagalong back in 2010 . However, I did not have a way to support multiple copies at the time. Then in 2016 I found this p6 ship which would have solved the problem, except the leading p3 part was too wide. Even using 117P9H3V0 didn't work: x = 33, y = 9...

Here's a way to support a field of 2c/6 tagalongs: x = 77, y = 134, rule = B3/S23 15b3obo11b3obo11b3obo$14bob2ob2o9bob2ob2o9bob2ob2o$14bo2bo3bo8bo2bo3bo 8bo2bo3bo$15b2obo2bo9b2obo2bo9b2obo2bo$14b2o3bob2o7b2o3bob2o7b2o3bob2o $18b2obobo10b2obobo10b2obobo$13bo2bo2bobob2o4bo2bo2bobob2o4bo2bo2bobob 2o$12...

By the way, anyone is welcome to propose descriptions for entries. They should be about 1 or 2 sentences (no more than 3) and should give a sense of the significance of the pattern. For example: 7. Width-12 c/6 orthogonal spaceship (Andrew J. Wade): The first width-12 c/6 orthogonal spaceship. This ...

By the way, why did "Trump {Bot}" get banned for no reason??? Bans happen for a reason. As far as I'm aware, all bans we've issued are for the user's posts and not for quotes by other users. We also give warnings before bans, and we start with at least one temporary ban before issuing a permanent b...

In addition to what Dave said, we need to write brief descriptions for the current entries. We want to come to a consensus on the finalized list before we start the voting thread.

Here's a cute p16 c/2 forward rake: x = 30, y = 29, rule = B3/S23 10b3o4b3o$9bo2bo4bo2bo$9b2o2bo2bo2b2o3$9b2o8b2o$6b2ob2o8b2ob2o$6b4o3bo 2bo3b4o$7bobo2b6o2bobo$8b2o2bob2obo2b2o$3o5b2ob2o4b2ob2o5b3o$o2bo4b2ob o6bob2o4bo2bo$o10b2o4b2o10bo$o3bo3b2obo6bob2o3bo3bo$o8b2o8b2o8bo$bobo 22bobo2$8bo2b2o4b2o2bo...

what input files were used for these oscillators?

Since those were from over 6 years ago, I doubt I could find the original input files. I'm sure they weren't anything special. Just a specified symmetry with a few cells set in the center.

Chris Rowett has found a new c/5 diagonal tubstretcher (shown here with two different supporting spaceships): x = 159, y = 98, rule = B3/S23 5b3o$4bo3b2o$3b2o3bo$2bo5bo$bob2o4b2o$2o2bo6bo$3b2o2bo$3b2ob2o$4bo$5b 5o$6bo2b3o2b2o$9bob2o2bob2o$9bo3bobo2bo99b2o$10b5o5b2o95bo2bo$9bo2bo2b o6bo93b2o2bo$20bo...

interesting puffer, isn't it the first 2c/5 puffer? If you want to know what elementary-based moving objects are known, you should look at the moving objects collection . According to the collection, this is the first 2c/5 puffer : #C 2c/5 dirty puffer #C Period 10150 (glide-reflective) #C Jason Su...

Chris Rowett found a new p120 2c/5 puffer. It can be reduced to this very small form:

[Removed] Regardless of whether it's true, posting what you claim are private messages between other users or credit card numbers of other users are violations of rule 1(b) . You should know this, because I reminded you about rule 1(b) less than four hours ago. For this reason, I have removed the o...

Wow you completely outclassed my version. I didn't use search tools. Did you? Probably not as well. I used JLS. I would not have been able to find those solutions without it. Can it interact with any of the p13 or p26 oscillators? It doesn't look very sparky, so I'm not sure how likely it is. If an...

How do I determine the equivalent of -fopenmp on my system?

It would depend on your compiler. I suggest searching the web for how to use OpenMP with your compiler. If you figure it out, it could be helpful to other users if you post your solution here.

qfind v1.4 released Over the last week I've made some modifications to qfind that collectively comprise versions 1.2 to 1.4. This post will describe the changes made since v1.1. As always, please mention any problems that you encounter. Options are now POSIX-like: For various reasons, I made option...

I second this. Skimmers, bubbles, and agar clearers should absolutely not be combined with grey ships.

My list of everything up to 34 bits coincides with this, but was missing the first 32-bit one (LWSS + tag-along). Do you remember who found that, or when, or if it has a name?

It's not surprising that you didn't have it. It was found by Hartmut Holzwart a little over a month ago.

Now, as far as I know, the two smallest un-buildable spaceships are the 29- and 30-bit c/3 ones. Indeed. I think the following are all of the known ships with no known synthesis up to 36 cells: x = 158, y = 213, rule = B3/S23 29bo$27b2o$27b2o$29bo$27bo$obobo3bobobo13b3o$26bo$4bo3bo3bo12b2o$28bo$ ob...

seven period shifts comibined with some spatial shifts. Here is a clean p14... Interesting idea, although the period is 26. The fuse travels at 6c/13.

Catagolue erroneously reports a p182 puffer. It's actually the p14 3c/7 blinker puffer followed by a 12c/26 fuse: x = 29, y = 188, rule = B3/S23 7b3o9b3o$7bobo9bobo$6bo2bo9bo2bo$6bob4o5b4obo$4b2o4bobo3bobo4b2o$5b3ob 2obo3bob2ob3o$3bo8bo3bo8bo$3bobo2b2obo5bob2o2bobo$2bo3b2o4bo3bo4b2o3bo $3bobo5bo5bo...

P14 3c/7 blinker-pair puffer found by Dylan Chen, the lowest-period 3c/7 linear-growth mechanism so far Very nice! Based on this and a suggestion by Hartmut Holzwart to look at different ways to stabilize the p28 wave, I was inspired to find these new puffers (periods 28 and 84): x = 284, y = 256, ...

Thanks for taking the challenge! Would your end piece work with odd width as well? I need two different backends for odd and even widths. For higher widths, much steeper descents should be possible!Optimizations welcome, obviously! Here is a width 11 chicken wire spaceship. There is one new compone...
