Abstract

We briefly survey some concepts related to empirical entropy -- normal numbers, de Bruijn sequences and Markov processes -- and investigate how well it approximates Kolmogorov complexity. Our results suggest \ellth-order empirical entropy stops being a reasonable complexity metric for almost all strings of length mm over alphabets of size nn about when nn^\ell surpasses mm.
