Re: Thread for basic questions

I believe Moosey was specifically asking about doing an apgsearch type search. Various such searches have been done, but I don't know up to what size bounding box. David Eppstein wrote gsearch for this purpose, and various other similar searches have been run by others.

Re: Small button pressing oddity

To register a "click" two things need to be true: When the tap starts (finger on screen) it is over a button When the tap ends (finger is removed) it needs to be over the same button It doesn't matter if you move your finger between steps 1 and 2 even if you move outside the button. As long as your...

You can't run searches in non-totalistic rules with gfind-pt.c without modification, i.e. combining the "latest gfind hack" EricG with the patches to gfind in gfind-pt.c

I'm confused why you are asking this question, but I guess I haven't been clear.

Re: Adapting gfind

Oh, for clang you need to change function definitions with "inline" to "static inline". Eg: change inline long hashFunction(node b, row r) { to static inline long hashFunction(node b, row r) { and the same for all the other function definitions with inline.

This rule contains a ship that travels at 10c/14o. It was discovered by wildmyron (possibly using LLS) in January 2018. I rediscovered the same ship independently later on, but I can't remember when.

If you find an additional segment, repeat similar searches with the newly extended partial, and continue until you come up with a ship or are unable to complete the partial.

Is there any way to make a script that checks for the longest-lived methuselahs in a rule, within an n-cell bounding box? This is definitely possible. The most optimized published program for methuselah searching is this one by simeks. It is CGoL only and written in C (and assembly?), but if you're...

Re: zfind discussion

The maximum speed that zfind supports is c/2. I don't know the algorithm well enough to explain this limitation. That's not quite true. Searching for a 2c/3 in B2ac3ae/S1c2i3i works just fine. It seems that sometimes the search requires higher widths than it should, but these work below, as well as...
