Does the "single row of still life" mean a continuous line of ON cells, as in the two examples given? If any pattern of ON and OFF cells is allowed in the row, then I don't think this counts as "unproven", due to the outline given in the unidiemsional spaceship thread showing that any constructible ...

Several problems I noticed so far... Here's a checkin that addresses most of these issues. A few of these changes are more complicated than I can handle right now, like these two from post180657: (new) Generations/g3s23-breeder.rle and (old) Generations/b3-s23-g3-spaceship-breeder.rle have inconsis...

Proposal to add a LifeWiki linkable definition of "transition", in the "transition rule" sense FYI to anyone interested -- I'm currently still planning to add something along the lines of the "green text" definition as a glossary article, a week or so from now -- on the grounds that the many curren...

For the record, here are the new Lua conversion scripts that I came up with for the Super algo. The old ones fail to recognize "Investigator" as a valid suffix, so they do Very Wrong Things when faced with any [Rule]Investigator pattern, telling the user that "Investigator" is not supported by Super...

Suggestions or assistance, please Anyone have any suggestions? Or would anyone be interested in making a smaller LifeInvestigator "Best Of..." collection, starting from this ZIP file, with comments in Andrew's new standard format -- and then we can put pointers in the comments of those files to say...

How can I configure a specific spaceship partial for WLS? It gives me an error when I try to configure it and search. That's ... an extraordinarily vague problem description. There are lots of subtle things that can go wrong at the configuration stage. It's easier for people to help if you provide ...

For 4-digit periods that are a 3-smooth number times a number under 1000, automatically add semi/tremi/quadri-snarks to the 3-digit periods to create the 4-digit period if it would result in a reduction... "Automatically" is going to be kind of a tall order, isn't it? Or rather, we could automatica...

This may be known, but I want to make a caterpillar... I kind of doubt that that specific G->2G + LWSS one-time seed constellation is known. It looks awfully complicated, though; there are much simpler constellations that can produce similar outputs, and can be chained in similar ways. It's not cle...

well, the clearance in not as good, but one has less timings to manage with this one reaction... So I assume one might make a smaller contraption for a signal converter. with a repeat time of 81 I believe. EDIT Got the test wrong somehow -- RT 81 it is... It's a little tricky to search through all ...

… but I suspect that the reaction in the BNE14T30 collides with the reaction behind it. … Yes ! You're alright. This is exactly what appends. Th BN14T30 have a back reaction which interferes with the following signal. Does anybody happen to know what prepended X-to-B would allow a repeat time of 12...

Yup. For example, it would be an ambitious but not impossible project to use the tools described in the Universal Computation chapter of the Life textbook (Chapter 9) to write a program that calculates the value of e and prints it out in the Life universe. There's plenty of other math -- combinatori...

OK, so my last converter can be used like this (shown at p120) ... ... Or smaller if initiated... The BNE14T30 edge shooter is advertised on the LifeWiki as having a recovery time of 120 ticks, but I'm finding the minimum repeat time is actually 126: x = 201, y = 126, rule = LifeHistory 200.A$198.2...

How about the "Limits of functions" item? It would take about three minutes to go through the math to check and verify, for example, one of Dean Hickerson's " unusual growth rate " patterns -- like the "Life computes pi" one, for example. Or condense a presentation like that into a minute or so, and...

Is there a synthesis that it can improve ? Hmm, probably. I haven't found anything yet that has an existing synthesis, so my example is a little bit contrived. Things like this might be more expensive to build without the new two-sided recipe: x = 48, y = 22, rule = B3/S23 2bob2ob2o28bob2ob2o$2b2ob...

Starting with BFx59H and then catalyse the H output with Eater1, I found a 3-states factory : nothing (original conduit+Eater1), Beehive, Block... Hmm. There's a path that's blocked by either of the two non-empty states, for a clean reset to "zero" of the three-way toggle: x = 133, y = 19, rule = L...

I'm used to Golly's version of Advance Selection at this point, so I tend to find LifeViewer's floating-selection behavior kind of puzzling -- I don't expect to need an extra [Enter] after advancing. Also, it's sometimes kind of hard to see what the advanced pattern looks like with some themes and s...

Yes, the Eater1 recovers in 3 ticks. But does the last reaction's cell count ? In this case, the RT is 4 ticks. Yup, Scorbie pointed this out several years ago. Probably the intention of the Did-You-Know from which this item was copied was something like " All known glider eaters take at least four...

NewLifeCA #48, 2 May 2024: new p7 spaceships, oblique wickstretchers, and teaser for new c/4 tech (sent via email 6:21am CDT, 2 May 2024) From this morning, here's another NewLifeCA contribution from Matthias Merzenich. New p7 Spaceships Period-7 spaceships are quite rare, so it's a bit of a surpri...

EDIT: It works! Does it? Better than before, for sure -- but with a p287 test input gun and a p143 drive gun, if you haven't run your pattern and confirmed a p41041 oscillator, you don't actually know if it works or not. Gun periods can be pretty much anything above the repeat time of the circuitry...

Here's the proof of concept for a stable universal regulator using the new L141 conduit: ... A beehive does occur, but it doesn't seem to mess anything up. That's a long way from universal, I'm afraid. You've picked drive gun and test input periods that are both a multiple of 13. If the test glider...

Block keeper...
It can also be used as a stable universal regulator

How?

It's probably about time for another NewLifeCA issue or two. I intend to write up an issue on the new c/4 diagonal technology soon (especially given today's new discoveries). Before that, there should be an issue covering the various other Life results... I've done a relatively brief email summary ...

is there anything stopping me from naming the L141 conduit "Lucy"? I can't think of anything offhand. L141 would be the only H-to-H conduit that has gotten a non-systematic name, though. Speaking for myself... I'm probably not going to want to expend much effort trying to remember that L141 = Lucy....

what makes the recently-discovered L141 so interesting? Details can be found here . Long story short, there's a provably universal but very limited toolkit of Spartan Herschel conduits that can be used to build self-constructing patterns -- i.e. circuitry that slsparse can automatically compile int...

NewLifeCA #47, 30 April 2024: catch-up issue for 2024 so far Every now and then, Real Life gets in the way of Conway's Life documentation. Sometimes this happens to such a large extent that it becomes unlikely that NewLifeCA newsletters will ever be able to get properly caught up with current event...
