Re: apgsearch v4.0
When terminating an instance of apgluxe right before restarting my Linux computer to fix the Internet connection, I glanced at the output and noticed the reporting of 17 switch engines in only 79424 soups at the end of my last haul. I then looked through the previous hauls and found similarly dispro...

Re: Thread for basic questions
Are you trying to search every single possible outer-totalistic rule? (Assuming your original post said "isotropic non-totalistic rule") I was thinking Apple Bottom may have only searched the rulestrings of the isotropic non-totalistic rules that weren't obviously exploding (e.g. no B1c). But my in...

Calcyman responded that Catagolue did not keep track of such a list. However, by February 2018, Apple Bottom announced conf...

Re: Random posts
Arbitrary patterns are just period 0 oscillators. This doesn't make sense. Yes it does, if you characterize a period-N oscillator as having the property that it remains the same at generations which are multiples of N and no others. Actually, adding "and no others" to the end of the characterizatio...

As the quartic equation Ax^4 + Bx^3 + Cx^2 + Dx + E = 0 can be reduced to x^4 + (B/A)x^3 + (C/A)x^2 + (D/A)x + (E/A) = 0 without loss of information (unless A is 0), you can just do a trivial substitution on the formulas Macbi gave to find its solutions: a -> B/A b -> C/A c -> D/A d -> E/A Expanding...
