When I run the command


C:\Users\Chris\Desktop\cfind_windows\ca_lib.exe cfind -v (1,2)c/3 -r R3,C2,S2,B3,N+ -w 5 --symmetry a


it gives this output:

Could you send me the full error shown when the program is run?

After fixing even more bugs, I am finally ready to release a completely re-written version of cfind 🎉.

The features and improvements made are below:
- Over an order of magnitude speed-up
- Support for searches with gcd(k, p) > 1
- Support for diagonal / oblique searches (note: oblique searches are ...

Back in 2020, I started a database for ships within 3-state Generations rules (including B0 rules). Now, I've finally gotten back to maintaining it again. Initially, I was going to create this thread after I release cfind, but I have no clue when that will be. Regardless, since I've begun running ...

While implementing B0 in cfind, I tried searching for a glide-symmetric c/2o ship in this rule.

Finally implemented photon searches in cfind and found a bunch of high-period photons (see https://catagolue.hatsya.com/census/r2b7t8s7t10/cfind_stdin )

Since I don't think wwei ever put it on the forums, I'll be posting a modified version of their spaceinvaders hacked apgsearch. It is for searching rules that can (but don't always) explode, and it does this by skipping soups when they exceed a certain generation number or a certain population ...

Lots of 2c/3o ships from cfind. Unforunately, apgsearch doesn't want to accept the ships as stdin, idk why.

If I'm not wrong, zfind is able to search for knightships. Does anyone know how the gfind search space is modified in order to allow for these searches?

I was working on implementing oblique / diagonal searches for cfind (unfortunately oblique searches don't work yet), so I'm curious to see how ...

yes, it does take some time to load because it needs to load the entirety of the multiple GliderDBs for each neighbourhood and number of states as well as the 5S databases.


Would it be possible in future to split this into several different pages, one per rulespace/database? That could make ...

Which neighbourhood and number of states does the new GliderDB have?


Previously I was maintaining a database of ships in 2-state R2 Von Neumann, R2 Moore and 3-state generations rules. I haven't updated them in quite awhile though. I'll probably make a thread for them some time soon (likely ...

I've finally gotten around to updating the GliderDB reader and the new link is here https://gliderdb-reader.vercel.app/ . [...]

For me, the link opens a blank page where nothing happens. Does anyone see a working page?
edit : it seems to work after reopening and waiting for several minutes ...

I've finally gotten around to updating the GliderDB reader and the new link is here https://gliderdb-reader.vercel.app/ . The code can be found at https://github.com/jedlimlx/gliderdb-reader .

Also B0 rules are now supported for the 5S database queries.

Hopefully I'll have more time to update it ...

I was also thinking about why some generations rules seem to have missing speeds.

I have managed to prove that for rules like Brian's Brain with no survival conditions, ships with k = 1 can only exist with period of 1 or period larger than the number of states. The proof is attached as a PDF ...
