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.

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...
