I'm from a parallel Earth with much higher coordination: AMA

Is Science Maniac Verrez a real series, for which HJPEV was named? Or was it invented for glowfic, with the causation going the other way?

Relatedly, are Thellim or Keltham based on anyone you knew? (or for that matter on celebrities, or characters from fiction written in dath ilan?)

Utility Maximization = Description Length Minimization

I don't see how to do that, especially given that it's not a matter of meeting some threshold, but rather of maximizing a value that can grow arbitrarily.

Actually, you don't even need the ways-to-arrange argument. Suppose I want to predict/control the value of a particular nonnegative integer  (the number of cubbyholes), with monotonically increasing utility, e.g. . Then the encoding length  of a given outcome must be longer than the code length for each greater outcome: . However, code lengths must be a nonnegative integer number of code symbols in length, so for any given encoding  there are at most  shorter code lengths, so the encoding  must fail no later than .

Utility Maximization = Description Length Minimization

What if I want greebles?

To misuse localdeity's example, suppose I want to build a wall with as many cubbyholes as possible, so that I can store my pigeons in them. In comparison to a blank wall, each hole makes the wall more complex, since there are more ways to arrange  holes than to arrange  holes (assuming the wall can accommodate arbitrarily many holes).
