Re: Golly script coding practice

I should probably mention that the code for the slow-salvo recognizer script, while it was taking the big step forward of being a million times faster, took a big step backward in terms of being less properly Pythonic. I took out the Glider class from the old code, and just did everything in terms o...

Re: Golly script coding practice

Now that we have a ridiculously long slow salvo to work with, it's suddenly clear that the recipe-minimizer-binary-Python3.py posted above... is in serious need of a rewrite. It does both the recognizing and the optimizing of a slow-salvo pattern in a seriously suboptimal way. Here's what the script...

Can someone give me all the slow-salvos from the O(sqrt(log(t))) pattern? Here's a pattern from an email I sent to Adam on April 4, 2010.

Re: Seeking Sawtooth Truth

Hacksaw The wiki article read: "the population in generation 1155(9^n-179) (n>=0) is only 977" which is clearly wrong, it gives negative results for 0,1,2. I assumed it was a typo, because DRH says "the population in generation 1155(9^n)-179 (n>=0) is only 977" which is correct for n=0, t=976 and p...

Re: Execution of Old Guns by Variable-Speed Firing Squad

But 43 and 229 are both prime, thus coprime, so the glider interactions happen at any possible timing, presumably making the result much complex. Possibly it's not as bad as you might think (come to think of it). I haven't tried this yet, because I'm on the road to Chicago for the day... but Jormun...
