Here are updates to two patterns in the collection. spaceship-types.rle (smaller (3,0)c/7; first (1,1)c/8; minimality proofs for (1,0)c/2, (1,0)c/4, and (2,0)c/5; corrected glider discovery year): #C A period p spaceship which displaces itself (m,n) during its #C period, where m >= n, is said to be ...

There are still a few patterns that need updating (at least traffic-light-hasslers.rle, c3-orthogonal.rle, c4-orthogonal.rle, and spaceship-types.rle; probably more). How soon should this be done?

I think you're asking to preserve north clearance (the past of the NE traveling glider) and some northeast clearance (to avoid the future of the reaction we're applying the spark to). Here is an example solution that continues mostly south and southeast and I believe will fit in if I've understood ...

I found two new perturbations that remove debris from the diagonal c/4 glider advancer convoy. One of them is a small spaceship that suppresses the blockade when the fuse is ignited. The second one is the smallest spaceship which suppresses the blinker produced when the advancer emits its glider. V...

Can a NE-traveling glider stream be turned around and shifted (a dirty solution would be fine) to complete become the input of a p488 advancer? x = 435, y = 491, rule = B3/S23 434bo$432b2o$433b2o242$434bo$432b2o$433b2o68$280bo7bo$279b2o5b2obo$ 279bobo3b2o2bo$283b2o2bo$281b5o$273b3ob2ob3o$273bo2bobob...

p36 gun reduced from 49x30 (1470-cell BB) to 47x30 (1410-cell BB) using a modification to the existing Jason's p36 mechanism that releases the glider using a different sparker layout Reduced further to 49x28 (1372-cell BB) using a custom sparker (smaller solutions probably exist): x = 49, y = 28, r...

If I'm not wrong, zfind is able to search for knightships. Does anyone know how the gfind search space is modified in order to allow for these searches? I was working on implementing oblique / diagonal searches for cfind (unfortunately oblique searches don't work yet), so I'm curious to see how thi...

It might also be possible to ignite the glider-advancer wick without the intermediate glider: x = 123, y = 97, rule = B3/S23 118b2o$118bobo$85b3o30bo$85bo35bo$86bo34b2o$85b3o25bo7b2o$85b3ob2o21b 2o6b2o$89bo2bo19bob4ob2o$92bo22bo5bo$79bo8bo25b2o3b2o$78b2o8b3o22b5o$ 78bobo2b6o25bo$69bo12b5o19b3o4b2o$6...

We also need some summary posts for some of the other group entries, such as engineered diehards and synthesis reductions.

Can someone write these? I don't have enough knowledge of those discoveries to do it myself.

> All that's left is to reflect and position the output glider stream so that it becomes the input stream That was a bit fiddly, but here it is. #C A diagonal c/4 period 1160 engineless puffer. ... Awesome! I just finished getting the chainable advancers to work at p632 while still allowing a glide...

What is the lowest period "engineless" rake that we can build? We should be able to get around p1000 using the following idea (shown at p1160). All that's left is to reflect and position the output glider stream so that it becomes the input stream: x = 1047, y = 2090, rule = B3/S23 1045bo$1044bo$104...

I've finally gotten around to updating the GliderDB reader and the new link is here https://gliderdb-reader.vercel.app/ . The code can be found at https://github.com/jedlimlx/gliderdb-reader . Here's a bug: it seems that you are still required to input a valid velocity, even when the "Ignore Veloci...

I'm more a "make a giant, messy solution" sort of guy or maybe occasionally a "optimize one direction of clearance at the extreme expense of every other metric" sort of guy. What are you hoping to use a "reduce"d version of this in? I could try to optimize the NW clearance similar to the other spar...

As David Bell has been mentioning, a fast-repeat-time advancer could presumably give much lower periods: x = 533, y = 554, rule = B3/S23 374b2o$374bobo$367b2o5bo$367bobo3b2o2bo$367bo11bo$370bo3b2o3b3o$370b2o 4b2o4bo$376b7o$377b4o$384bo$383b4o24bo$387bo22b2o$382b6o22bobo$376b3o 3bob2o$376bo5bobo28b2o...

Some very preliminary searching can turn it e.g. at that first NW branch: x = 27, y = 42, rule = B3/S23 11b3o$11bo$2bo11bo$b2o8bo4bo$bobo8b3o$9bo6bobo$4b2o2bob2o6bo$5bo2bo2bo 7bo$4bobo13bo$3bo4bo2bo8bobo$3bo3b2o$3b5o3bo10b2o$4b3obo4bo9bo2bo$5bob ob2ob3o$4bo2bobob4o7b2o2bo$4bo17bo$4bo3bo$b2o3bobob2o...

New rules: No posts that could possibly be viewed as negative. No making fun of other users. No quoting users with account ages less than 6 months.

The reason for the last rule is to avoid scaring off new users with unexplained attention to their posts.

I removed some of the glider redirection convoys, and so reduced the period of the diagonal c/4 puffers. As a fun exercise, I found a complicated cleanup convoy that works regardless of the period mod 16. Here is the resulting clean p3532+4N rake: #C c/4 diagonal p3532+4N rake #C #C To increase the...

I created a pre-pulsar hasslers page for pre-pulsar hasslers that aren't shuttles. Can someone please add the following oscillators to that page: x = 289, y = 307, rule = B3/S23 104bo$103bobo$102bobobo$102bobobo$101b2obob2o$99bo2bobobo2bo$99b2o3bo 3b2o$102bobobo$97b5o2bo2b5o$96bo5bobobo5bo$95bobo3b2...

This appears to be the basis of a fully configurable diagonal c/4 puffer. Excellent! Here is a refinement to more clearly demonstrate this mechanism: #N c/4 diagonal p4388+4N dirty rake #C To decrease the period by 4N, move #C box A diagonally southeast 2N cells. #C To increase the period by 16N, m...

when using synthesise-patt.py inside golly, how do I show all results and not only one? The version of synthesise-patt.py from here seems to work fine for me. I tested it on the R-pentomino and got 267 results. The pattern was zoomed in on the first synthesis, but I could simply zoom out to see the...

Here's a result I found, I don't know it this could be cheaper to rebuild than the pond and biblock?... Edit: Oh, you can turn the emitter around, that looks more promising: x = 46, y = 43, rule = LifeHistory 28.2A11.2A$28.2A2.3A.3A2.2A$32.A5.A3$26.A.A5.A.A5.A.A$26.2A.A3.2A.2A 3.A.2A$29.A3.2A.2A3.A...

It's a bit disappointing that it is so large and slow. Having to pull those loafs out from the fuse wastes space and especially time. Cleaning up the debris would make it even larger. I was hoping to beat the old adjustable puffer with its 4508 period, but this doesn't do it. At least it gives a ne...

I think this is the basis of a simple variable period diagonal c/4 puffer. This is essentially the basis for your original p4508+32N rake (version in link is period 6108). I'm wondering if there is a way to perform the reignition much faster than p4508. Much of the time in the original is taken by ...

2c/5 even searches completed for pop 60 in all five phases: max memory 97.8 GB, total time ~26.5h. Found only doubles of 30P5H2V0. Thanks! Interesting (?) that it took so much less time than the pop 57 odd-symmetric search. Was this the last spaceship min pop search you had in your queue? the weigh...
