Thanks! I assume by the .exe extension that you are on Windows. Did you use the pre-compiled version available here , or did you compile it yourself? If you compiled it yourself, can you tell me what compiler you used and any compiler flags you included? Yeah, it's precompiled. Thanks again! When y...

What row did you start from? There's that loose connection so that I suspect a width-10 odd-symmetric search from the following row (highlighted white) might give alternate solutions (assuming you didn't start from there).... I'd try the search myself, but my "4-core and 7 years ago" laptop for som...

When looking through honey-farm-hasslers.rle in the Golly pattern collection, I noticed that many of them aren't on the honey farm hasslers or honey farm shuttles wiki pages. Here are the patterns that seem like they should be added: x = 488, y = 435, rule = B3/S23 35b2o6b2o$31b2obobo6bobob2o$29bo2b...

I used qfind to extend my partial, and I ended up with this Awesome! Since you have a 12-core pc, make sure you are using the -t option to set the appropriate number of threads. What row did you start from? There's that loose connection so that I suspect a width-10 odd-symmetric search from the fol...

The absolute ideal is probably a fuse ignition by a passing p4 catalyst-type ship... Is it too much to hope for a lucky still life output from the fuse-burning-ending reaction? E.g. if it could leave a loaf by the back end of the now-unlit-fuse like so... x = 109, y = 177, rule = B3/S23 8b2o$7b2o$9...

Did you remember if you ever attempt a symmetric search for that p7 soba-based backrake idea? I can only find an asymmetric partial result here.

I tried a b2f search for a 3c/7 back rake, as crazy a long shot as that is. I still think the following idea might be the best shot at a p7 backrake: Here's an idea for finding a period-7 3c/7 rake that might be feasible: The glider releasing reaction in the p21 rake is more reliant on the spark fr...

Would it be possible to give a reasonably detailed summary/outline (aimed towards beginners) of what kinds of searches are feasible with current software tools, as a function of available computing resources and willingness to wait for the result? This is getting a little beyond "basic" questions. ...

#C A diagonal c/4 period 76 sideways rake. ... Thanks! I thought it must be possible, and now we've already justified the existence of this new and absurdly large puffer engine. The c/4 diagonal status table was starting to get a bit too green, which belies the fact that we don't know much above th...

I got something like the second solved but it's not clear if it will actually be useful as the branches on that back (east) side are pretty big and possibly in the way. Wow, that's some crazy branching! However, I think it will be useful. The following high-period chaotic puffer seems to have a bas...

I want to get back to this soon. I've just been busy. This post is an attempt to make a commitment to finalizing the list. I'll delete this post later when I actually get something done.

I have fixed the issue with the Tumbling T-tetsons; it is now in the p8 section. I have also moved a few more oscillators around since they were mis-categorized. Thanks, but now the rule says "OtherLifeHistory", which gives a LifeViewer error. While I could duplicate Karel's p15 into the "delayed d...

here is my current stamp collection of p3-16 sparkers, sorted by period and spark type. (Some sparkers that give off multiple sparks appear multiple times in this collection) Great work! Three issues that I see: The last sparker in the p7 delayed domino row is actually p8. Karel's p15 can also act ...

I am curious what holds it up. The greatest historical impediment to LLSSS search effectiveness has been memory limits but it's gotten a lot better with the one-bit-at-a-time changes and these days I am doing most of my human-guided solving with searches limited to 8 GB (I have other, longer, less-...

Alternate back edges to the recent c/4 diagonal puffer engine with slightly different sparks could give variant puffer engines that behave differently. Here are two related partial results, the first probably being easier to solve, but the second giving a more resilient engine: x = 168, y = 29, rule...

Just a few minutes later one of the other searches dropped this: #C [[ TRACK -1/4 -1/4 ]] x = 74, y = 102, rule = B3/S23 28b2o$28bobo$28bo$31bo$31b2o$31b2o$30b2o$26b2ob2o$26bo4bo$26bob4o$30b 2o$31bo$30b2o$26b4obo2bo$25b2obobobo$27bo4b3o27b2o$50b3o9bobo$32bo17bo 2b3o6bo9bo$7b3o41bobo16b2obo$7bo22b2o...

I guess it just seems rather hemmed in, stuck searching upward, and subjectively the rate at which search results were lengthening with widening windows seemed poor. Alas it's crummy subjective metrics all the way down. I feel like it wouldn't be too hard to move that center branch out of the way o...

I don't think this is useful, but the smoke can reflect a glider (of course, the glider would need to be placed there very precisely): x = 74, y = 102, rule = B3/S23 28b2o$28bobo$28bo$31bo$31b2o$31b2o$30b2o$26b2ob2o$26bo4bo$26bob4o$30b 2o$31bo$30b2o$26b4obo2bo$25b2obobobo$27bo4b3o27b2o$50b3o9bobo$3...

That sparker with that clearance is quite demanding. Some preliminary searches (8 GB) do find longish partials but they don't look very nice to me (mostly wide and mostly getting wider as they go), e.g.: x = 74, y = 53, rule = B3/S23 28b2o$27b2o$29bo$31b2o$30bo2$29bo2bo$26b2obo$25b2o4bo$27bobo2bo$3...

Here's an idea for a p12 c/4 diagonal backrake that might be possible, but it would require the discovery of multiple, likely difficult components: x = 265, y = 57, rule = B3/S23 28b2o68b2o68b2o68b2o$27b2o68b2o68b2o68b2o$29bo69bo69bo69bo$31b2o68b2o 68b2o68b2o$30bo69bo69bo69bo2$29bo2bo66bo2bo66bo2bo...

Here's some detail on how I found the recent puffer engine, for those who are curious. The partial result posted here was found with JLS . I first tried to find a puffer that emits a 4-line (beehive predecessor). Nothing I tried was working. I then remembered how a pre-TL can sometimes interact with...

Here's an idea for a p12 ( Edit: originally I incorrectly claimed it was p16) c/4 diagonal backrake that might be possible, but it would require the discovery of multiple, likely difficult components: x = 265, y = 57, rule = B3/S23 28b2o68b2o68b2o68b2o$27b2o68b2o68b2o68b2o$29bo69bo69bo69bo$31b2o68b2...

Here is a diagonal c/4 period 52 rake Wonderful! When I first found the engine, I was excited to see that it seemed to have a base period of 52 and was hopeful that such a rake could be constructed. It turned out more difficult than I anticipated. I took the liberty of compacting the components of ...

For the same reason that Antonin believes they should be posted in a separate thread. I didn't, and still don't, understand those reasons. I would probably need it explained in a different way. Right now I don't see how the c/4 diagonal posts negatively impacts the posting of other content. Also, i...
