[Article] Can Evolutionary Computation Help us to Crib the Voynich Manuscript ?

[MarcoP]

Everything else is - without help coming from experts in other disciplines - just a speculation.

Experts already pointed out that entropy excludes a simple substitution cipher of an ordinary language. E.g. Lindemann and Bowern, Character Entropy in Modern and Historical Texts, 2021 (but this is known since Bennett's 1976 book):

At the character level, Voynichese is strikingly different from any other text in the Wikipedia and Historical corpora. The character set size and frequency of characters is conventional, but the characters are combined in an extremely predictable way, as indicated by an unusual conditional character entropy that is distinctly lower than any of the 316 comparison texts.

...

If Voynichese is encoded text, it must be more complex than a simple substitution cipher. A simple monoalphabetic substitution cipher will have absolutely no effect on conditional character entropy, because the same characters simply shift places with one another.
