Re: SymSAT, another SAT-solver-based search package
I defininitely agree that a standard way to specify SAT problems would be useful for CA problems, however I think it's hard to represent it without writing code. From experience: I've tried to use ikpx, lls, and lsss for various problems (mostly unsuccessfully). For most, I had to write code to prod...

Re: cellular automata according to Max Planck
The application of CGOL rules does require a grid and a lot more compute power than you will get from a ZX81. Not quite true: the ZX81 can be programmed to simulate life at plenty of generations per second. Based on my knowledge of z80 assembly, I'd guess that you could easily get 100gps - and when...

Re: Oscillator Discussion Thread
I now feel silly because I didn't actually see that it was just a p7 that sets a bit, and the "p5 component" that LLS found is actually just stable... LLS gave me exactly what I asked for, I guess. Re-running with "c 0 1" to see if anything else pops up - I thought I had something earlier that had a...

Re: A new spaceship search approach
I don't think it's multi-threaded like ikpx and qfind, and I'm not sure how well the search space can be split up. It does require a seedcolumn, so you could still split the search up based on that. The shell scripts have a $threads variable which is passed to the rust program. Often, however, one ...

Re: dr Discussion Thread
Since I'm using dr to smash oscillators together I need to run it a lot of times. Depending on the specific oscillators, a single pair can take from hundreds to thousands of runs, with each run taking (again depending on specifics) around 5 seconds on average, or a couple hours for the whole run. I ...

Excellent! I'd love to know more about your methodology. How do you find the stable background? Do you test all phase combinations? Even for periods with gcd=1, some phase combinations will cause the pattern to self destruct, while others will result in a phase shift oscillator ... Also, do you use...
