Re: is this c/10 spaceship known?

The copperhead has 4 predecessors that fit withing a 6x11 rectangle with symmetry. Finding the ship this way takes ~1 hour. x = 11, y = 39, rule = B3/S23 2b3ob2o$o3b2o2b2o$4obo4bo$4obo4bo$o3b2o2b2o$2b3ob2o6$ob3ob2o$4o4bobo$ 2o5bo2bo$2o5bo2bo$4o4bobo$ob3ob2o6$2b3ob2o$4o4bobo$obo4bo2bo$obo4bo2bo $4o4b...

Re: zfind discussion

Your changes to make it handle searches faster than c/3 slow down the search. I thought it probably would. So, when checking a row, is 3 the ideal number of generations to look back for a predecessor? As, you noted, only looking back 2 generations isn't as fast. Does looking back 4 generations also...

Re: zfind discussion

Though the search still seems a bit slower-- around 100 seconds for w5p10k1v instead of 80 (but I'm running several instances on different cores.) 100 seconds is way too slow, it should be close to 20. Your compiler is probably not optimizing it correctly. Compiling with gcc -O3 gives 19 second sea...

Re: zfind discussion

Your changes to make it handle searches faster than c/3 slow down the search. Modified version below, a few small additions: greatly reduced spam added symmetry modes a = asymmetric g = gutter can search for speeds faster than c/3 #include <stdio.h> #include <stdlib.h> int sp[8], *gf, *gb, *gl, *gs;...

Re: is this c/10 spaceship known?

It looks like this thread was linked from somewhere, since it now has over 40k views. If anyone is interested in how simple it was to find this spaceship run the following c code with arguments: b3s23 w5 p10 k1 v This was the exact program used to find it. #include <stdio.h> #include <stdlib.h> int ...

Re: is this c/10 spaceship known?

Edit: How long did it take to find the ship? I just ran this search in gfind and it refound the ship in a little over an hour. It's really amazing this wasn't found sooner. This is why I suspected a bug in gfind, it is small enough that someone should have found it by now. The search takes 19 secon...
