Re: Thread for your unsure discoveries
I was not aware of that one, but the standard 3glider method works just as well. Both insert at the minimum possible separation. Here are the other LWSS, MWSS, and HWSS syntheses I know that can insert spaceships at minimum separation (14, 16, and 18 generations respectively). Two had to be slightly tweaked:gmc_nxtman wrote:Is this fromthefront LWSS inserter known? ...

Re: Thread for your unsure discoveries
chris_c's collection on GitHub is pretty darn current, and fairly easy to go look things up in  you don't have to download the whole collection to find a specific gun.BlinkerSpawn wrote:On a related note, where can I find relativelycurrent versions of the gun collection?
(For the variable guns you might have to make some adjustments to get an actual gun pattern, though. That would be a good lowpriority project if someone wanted to tackle it, building out actual RLE for each gun period up to 1000 where there isn't an entry in the fixed folder.)
If you just want to see if a newly built gun is better than what's in the collection, just multiply the allphases bounding box length times width and check that against the number for that period, in the README on the landing page.

I swear I've seen this before. Wasn't it utilized in one of Guam's sparktoG converters, or something along those lines? (Good work if you [re?]found it on your own, by the way )drc wrote:This is bugging me:Code: Select all

EDIT: perhaps it was brought up in a discussion thread relating to said converters? Unfortunately I can't find anything with the forum search (partially due to "glider" being ignored as too common, lol), but if anyone else is curious I very clearly remember one post in said thread containing both of Guam's converters

Re: Thread for your unsure discoveries
Are these 3glider synthesis for Acorn, Multum in parvo and Thunderbird known?
At least here they are listed as 4 glider synthesis in
http://codercontest.com/mniemiec/glider4.htm
But here the switch engine is listed as 4Gsynthesis even though 3 is known (http://www.conwaylife.com/wiki/Switch_engine).
Also the wiki states them as 4 glider synthesis (http://www.conwaylife.com/wiki/Thunderbird, http://www.conwaylife.com/wiki/Acorn) For Multum in parvo it is not stated (http://www.conwaylife.com/wiki/Multum_in_parvo)
Additionally I found a 3 glider synthesis for 7468M:
and Thompson's 6bit methuselah
For the 7468M no synthesis is reported, for the latter one only a 6G synthesis.

Re: Thread for your unsure discoveries
I don't believe so, but the synthesis wiki hasn't been updated in quite some time (I think waiting for a robust way to handle new records semiautomatically) and the Methuselah section in particular hasn't really had much attention paid to it; most synthesis attempts are focused on stilllifes and oscillators.2718281828 wrote:Are these 3glider synthesis for Acorn, Multum in parvo and Thunderbird known?
Re: Thread for your unsure discoveries
I know of one different 3glider synthesis for Thunderbird, found by Extrementhusiast on 20150704. All the others are improvements. Very nice! I was not aware of 7468M; I will add it. I am trying to list all important methuselahs below 10 bits. (Unfortunately, I've been somewhat mindbogglingly slow in updating my site, but things are starting to come together, it shouldn't be that much longer.)2718281828 wrote:Are these 3glider synthesis for Acorn, Multum in parvo and Thunderbird known? ...

Re: Thread for your unsure discoveries
I am working on the enumeration of all 3G reactions, and I got all the results by looking at the ashes. The mentioned reactions are only representatives, for some there are multiple options. For the Thunderbird I have e.g.:I know of one different 3glider synthesis for Thunderbird, found by Extrementhusiast on 20150704.

Re: Thread for your unsure discoveries
An exhaustive examination of all 3G reaction has, to the best of my knowledge, never been done. Dave Buckingham did a fairly comprehensive study of them back around the 1980s or so, but the fact that occasional new 3glider syntheses have come up over the past few decades (e.g. pentadecathlon, bipond, infinite growth, and switch engine, plus the ones you posted here) show that he didn't find all of them.2718281828 wrote:I am working on the enumeration of all 3G reactions
There are three things I'm personally particularly interested in with regards to 3 glider collisions, which haven't really been studied in depth  syntheses of pseudostilllifes (because few people care about them, so they are frequently overlooked), constellations of 2 objects (because these are frequently used in larger syntheses, and making 2 at once can save a glider or two off the recipe), and 3glider syntheses of certain useful sparks  hopefully with no additional debris, although in some cases, the sparks can be useful enough that an additional cleanup glider or two can be tolerated.
I have a few hundred sparks (mostly from Buckingham's research), and around a thousand constellations (mostly from mine), but those aren't very well organized, and come from haphazard, rather than systematic research.
Re: Thread for your unsure discoveries
There are a lot of people who will be interested in this. You should discuss your methods in this topic. Someone might be able to give some helpful suggestions. Personally, I'm curious how you plan to deal with the 2glider collisions that release gliders (e.g., 2glider mess and Bheptominoes).2718281828 wrote:I am working on the enumeration of all 3G reactions.

Re: Thread for your unsure discoveries
Hear, hear! For example, do you happen to be able to confirm Extrementhusiast's result that there are 1,546 cases where the three gliders all interact for the first time on the same tick?Sokwe wrote:There are a lot of people who will be interested in this.2718281828 wrote:I am working on the enumeration of all 3G reactions.
Luckily there are only a few collisions that do that  a total of seven, including the three Bheptomino outputs and 2glider mess that Sokwe mentions, plus the two kickback reactions and the TL+glider reaction. The kickback collisions are relatively easy to get a complete enumeration for, but the Bheptominoes and the others seem fairly painful.Sokwe wrote:Personally, I'm curious how you plan to deal with the 2glider collisions that release gliders (e.g., 2glider mess and Bheptominoes).
Even an enumeration that excludes the toughest cases would be really useful. @2718281828, does your analysis start from twoglider collisions, or are you using some other method?
It looks like you've recorded a good large subset of threeglider collisions already, to find those methuselah syntheses. Does anything happen to have the ash signature of this part of a loafer recipe?
Code: Select all
x = 39, y = 31, rule = LifeHistory

D.D$32.2D$33.D$36.3D$36.D$37.D5$.C$.2C$C.C6.C$9.2C$8.C.C!
Given a good database of threeglider collisions, though, it should be possible to reprocess and reindex it in all kinds of different ways.
Edit: I fixed your quotation formatting. Sokwe

Nice work, this is very interesting!2718281828 wrote:I am working on the enumeration of all 3G reactions.
Instead of reducing the loafer synthesis, perhaps we could try reducing the [url=chttp://www.conwaylife.com/forums/viewtopic.php ... 325#p46308]copperhead synthesis[/url]. I tried and failed to reduce it using 3 glider collisions, but I'm wondering if we can with a more complete set. So do you have any collisions that creates these patterns?:

For this I have found these four different options:the third will not definitely (I have actually already found some collisions for the third, but none of them are compatible with the copperhead synthesis).
