A Cipher Thought Experiment

[nablator]

I thought this text had been deciphered since then.

No, and byatan disappeared from the forum without giving additional clues nor ciphertext samples. Even if this cipher is not solvable because the sample is too small (I agree with oshfdk), I would be very much interested in a good algorithm or software for solving this type of cipher (a prime suspect for Voynichese).

I can generate longer samples of ciphertext from a possible decomposition in 3 strings of the words of byatan's cipher (one per plaintext letter), probably not perfect for solving byatan's cipher, but it doesn't matter if we want to solve this type of cipher in general and just need a longer ciphertext sample to test the software.

I wrote a solver to optimize the decomposition in 3 parts of the words but it gets stuck in sub-optimal situation very often and I can never know how far it is from the optimum (a frequent problem with the Hill Climbing algorithm).
