Re: apgsearch v4.0

Verifications are done sequentially, not in parallel. As such, if you have many cores, they'd be under-utilised if verifications were enabled by default. (You can enable this by setting -v 5 in the command-line arguments.) I've found that verifications are so quick that the idle cores aren't worth ...

Re: apgsearch v4.0

stupid question: How do you end a search prematurely? If you're using Cygwin or you're on Linux or Mac (anything POSIX, apparently), then type "q" and wait some number of seconds. Your partial haul will be submitted and the search will exit gracefully. As 77topaz mentioned, there are cases where th...

Re: apgsearch v4.0

// Disable verification by default if running on a HPC; // otherwise verify three hauls per uploaded haul: if (verifications < 0) { verifications = (parallelisation <= 4) ? 5 : 0; } Why have this? Why shouldn't high-performance computers do verifications? With the increase in CPU cores these days m...

Re: Soup-searching as a video game (ethicacha/apgacha)

You can really lower the barrier to entry for non-mobile (i.e. computer) players by making it a browser game . The soup search could also run in the browser by compiling it to a WebAssembly target. It appears that Webassembly has the necessary instructions to handle 64-bit Lifelib (yes, it's not 256...

Re: apgsearch v4.0

Should I switch to v4?

I recently started running my apgmera install again and I see very few people are running v3.28. Should I upgrade to v4.0? Is the new version faster or more correct? When I asked this question about a year ago, the answer was that there wasn't a compelling reason to upgrade.

Re: apgsearch v4.0

I recently started running apgmera v3.28 again after many months idle. It's generally running with 2-8 threads depending on what else I'm doing.

For b3s23/C1 is there an advantage to running v4? Is it faster or better?

Yes, it got at least as high as number 8 on the front page of Hacker News. HN drives traffic the way Slashdot used to.

Re: Reaction types and terminology

Yes, the block keeper and blinker keeper reactions fall into this category. There are several examples of each, and even a variable-period gun based on the blinker keeper. Ahh, thanks. I found the writeup on the blinker keeper, but nothing about the block keeper. What about every reaction that thro...

Confirming the report from Ajax that "Select All" on Firefox adds leading spaces to the copied RLE text which then does not correctly paste into Golly.

Re: Thread For Your Accidental Discoveries

It's a shame that soups like this from Andrzej Okrasinski's census were never made public (apart from the P2 Lightbulb); Several rare oscillators like Tim Coe's P8 and the P5 Fumarole occurred naturally, and the soups might have led to improved glider syntheses. He did release a results document on...

Speed optimization, automation of golly perl scripts

I'm guessing your script has lots of g_run() calls mixed up with lots of editing calls? Exactly. If so, put a g_new() call at the start of your script -- that will prevent lots of temporary files being created and the script will run faster. This solution assumes your script is creating a pattern r...

Is there a way to manipulate Golly's Undo/Redo setting from a Perl script? In Golly 2.1, some scripts can generate GiBs of undo info, eating disk space and slowing down the script. I've just written such a script. It would be useful to be able to save the state and disable Undo at the start of the s...
