Re: Spaceship Discussion Thread

Nicolay's modification of WLS is, as the name suggests, a version of WLS (based on v0.62) by Nicolay Beluchenko. It includes several very useful features, namely: the retention of toroidal boundary conditions only present in earlier versions of WLS, a method of hashing solutions which allows discon...

Re: Thread for basic questions

What is the smallest object that has no known glider synthesis? All spaceships up to 34 bits are solved, except 2* 31- 32-bit c/2 orthogonal ones, 3* 26-, 29- and 30- bit c/3 orthogonals, 3* 27-, 32-, and 33-bit c/4 diagonals, and 3* 34-bit B29s w/glider tag-along.

How about if greyships get their own collection, like maybe a ZIP archive in Very Large Patterns in Golly's Online Archives? I would really like to see this.

The width 12 (1,0)c/6 search was a success. It showed up last night but I didn't realize it was a spaceship until today. Great work! I was always pretty sure that a width-12 c/6 ship existed, but I honestly expected it to be a bit shorter. It's still possible that a shorter ship exists, but I'm muc...

Re: Help me finish this c/8 search

I still regularly get crashes on the original qfind-c8.cpp with multiple threads. I believe it may be because in function success() both srows and ssrows are grown with realloc() . However I think that memory is shared between the threads and it's possible that realloc() might move the memory block...

Re: qfind - a spaceship search program

How can I eliminate duplicate results? If you are finding a large number of spaceships, you will probably want to use the 'x' command which prevents the program from printing spaceships during the deepening stage. This will eliminate many of the duplicate patterns, but not all of them. There is no ...

Sorry for my noobiness at spaceship searches (I don't use search programs other than apgsearch), by why are spaceship searches done by width? Calcyman gave one good reason, but there is another. It seems that these long, thin searches are generally the most effective. That is, you can get long part...

replaced all the instances of omp_get_thread_num() with 1.
I think that you would need to replace them with 0, not 1. However, I recommend getting a compiler that supports openMP.

A weird thing happened when searching for a 2c/6o. A c/3 (unsimplified) popped out. If you want to find a period-6 ship, qfind might be better than zfind.

It has a few weak sparks, so it will probably give some smaller LCM oscillators, although I'm not sure if it...
