Another thing: This is the slowest non-engineered spaceship, measured by the distance it travels in any direction in a given time: 1/10 of the orthogonal distance across a cell per generation. (Since the Corderships are diagonal C/12, they travel √2/12 cell-lengths per generation.)

Re: is this c/10 spaceship known?
Just to be nit-picky, I would consider Corderships engineered, because they consist of multiple switch engines strategically placed to cancel out each other's debris.gameoflifeboy wrote:Another thing: This is the slowest non-engineered spaceship, measured by the distance it travels in any direction in a given time: 1/10 of the orthogonal distance across a cell per generation.

Re: is this c/10 spaceship known?
zdr's search program crashes upon trying to search for a 5c/13 orthogonal ship or on trying to refind the loafer. Still quite impressive little program though, output this partial in less than a minute or so and then returned that there were no solutions for odd symmetric at width 11:
I'm not knocking it or anything (it's already given us a great new spaceship velocity, which is no small accomplishment), just reporting that something prevents the program from being able to do those searches.

Use gcc. It fails to compile in g++.gmc_nxtman wrote:How do you compile this?
I tried it out and noticed a few things:
- It uses up a lot of memory, especially at higher w.
- The program crashes for some values, like w>=10, or p=5, k=2. I think I have an idea why w>=10 crashes but there doesn't seem to be a quick fix.
- I don't know what v does. It doesn't seem to affect the search in any way.
- If I have it right, the rule is entered like b3s23 (you can leave it out), w is width, p is period, k is orthogonal displacement (displace spaceship by (k,0) after p gens), l is level/how far to search, u is a flag meaning odd bilateral symmetry (don't put it in for even bilateral symmetry), and I don't know what v does.

It seems to crash whenever the speed being searched for is too close to c/2 in general which is quite unfortunate because speeds like 3c/7 are quite interesting - but maybe there's a way that can be fixed.
I found this 3c/11 front engine using zdr's search - the back end of the 19 cell front section only requires interaction on two consecutive ticks, both of them being extremely simple:
Code: Select all
x = 9, y = 29, rule = LifeHistory

Re: is this c/10 spaceship known?
This seems to be a major limiting factor for the program. It needs to be able to allocate 2^(3w+4) bytes. At width w=10 this is more than most operating systems will allow, so it crashes.\FractalFusion wrote: It uses up a lot of memory, especially at higher w.
Edit: It also crashes for me when p < 3*k.

Re: is this c/10 spaceship known?
Actually those warnings will give bad printouts. They may also cause stack problems. It is very important to change those instances of %d to %ld. (On OSX, sizeof(int)==4, sizeof(long)==8).

Re: is this c/10 spaceship known?
In case anybody cares, I tried putting Copperhead into my multi-colored Life search program (that handles multi-colored Life variants such as 2-color Immigration and 4-color QuadLife), and it was able to confirm that all hybrid forms fit the following template - i.e. all 'a' cells must be of one color, all 'b' cells must be of one color, etc., and these colors may or may not be distinct. Sadly, there are no complex multi-color interactions to produce colorizations resulting in periods that are higher multiples of 10.
