### Re: Thread for basic questions

For which oscillator periods do we actually know the smallest oscillator by population? All of the results I know about were compiled from various sources by Mark Niemiec here with at least these two corrections: I don't think all 10-bit patterns have been tested as claimed in the table (it's diffi...

### Re: LLSSS min pop search results spam

Can we prove that 25P3H1V0.1 and 25P3H1V0.2 are the smallest c/3 spaceships? If you mean the smallest period-3 c/3 spaceships, this has already been shown as confocaloid noted. If you mean c/3 spaceships of any period, then we most certainly cannot prove these are the smallest. To do so would I thi...

### Re: Spaceship Discussion Thread

I have confirmed using Nicolay Beluchenko's version of WLS (WLS 6.3) that 58P5H1V1 is the only p5 c/5 diagonal spaceship up to diagonal height 12. I also confirmed that there are no symmetric c/4 diagonal ships in a 17x17 bounding box and no 2c/4 even glide symmetric ships up to width 16 (not counti...

### Re: LLSSS min pop search results spam

Is it two ships because they could exist as they are separately? Is it one ship because they are connected by an over-population non-birth with 4 neighbors? That's two ships forming a pseudo-spaceship . Edit: you probably shouldn't worry about filtering such objects automatically. Most of your min ...

Here's a new c/5 diagonal tagalong for 86P5H1V1 that I found while searching gutter-symmetric diagonal width 31...

2c/4 odd to pop 32 completed very quickly with very little memory... 2c/4 even to pop 48 is out of range (max is 4x9-1 = 35). c/3 odd to pop 52 finished pretty quickly Thanks! If you find the time, I would appreciate if you could run the searches up to period 4 that are likely to complete quickly (...

I have confirmed using Nicolay Beluchenko's version of WLS (WLS 6.3) that 67P5H1V1 is the only p5 c/5 diagonal spaceship up to diagonal width 16 (the ship itself has diagonal width 15). That's not too surprising since it seems like a width-16 ship would have already been found by ikpx2 if it existed...

### Re: Soup search results

I manually decreased the bounding box area by 16 and increased the lifetime by 1.... I increased the lifespan by 1 without increasing the population. x = 19, y = 15, ... It bothers me slightly that you didn't apply some of those bounding box reductions in the second case: x = 19, y = 13, rule = B3/...

### Re: LLSSS min pop search results spam

Unfortunately the current exhaustive population search absolutely does not work once you have enough population to make two separate ships. To make sure I'm understanding this correctly in the symmetric case, does that mean the search breaks down once you have enough population for just one ship on...

### Re: LLSSS min pop search results spam

As an example I think the c/3 gutter bound of 50 is not know to be exhaustive. We know there are no 49 cell gutter ships from the census I did up to 49 but there could I believe still be other pop 50 gutter ships. On this note, the only known 50-cell c/3 gutter "ships" are actually just two 25-cell...

I've just now remembered that I had a question about the table. Some of these are known unique (or exhaustive in the more general case) and some I think are not.

### Re: LLSSS min pop search results spam

Could this method be used to find the smallest completion to a partial result, or is it fundamentally limited to searching the whole space? Theoretically maybe, practically probably not. Maybe for very small completions and/or for very friendly geometries (like c/2 or c/3). It would primarily be us...

### Re: Spaceship Discussion Thread

given that we have stabilised the corder engine, why can we not stabilise the pi engine? Such a spaceship would have a period greater than 10. If we allow ships that are not the minimum period, then we already have all orthogonal and diagonal speeds (see Speed Orthogonoid and Speed Demonoid ). slow...

### Re: Spaceship Discussion Thread

Just curious, are we more likely to find a spaceship with speed: c/8o, c/9o, c/9d, 3c/10o, c/7k, c/8c? Note that c/7k and c/8c are very non-standard. You should rather write (2,1)c/7 and (3,1)c/8. This is a very hard question to answer. Without knowing anything else I would say lower period is more...

RT114 B-G Nice find, although it is a rediscovery (first posted here ).

It might be worth revisiting that decisi...
