computer modelling of cryptanalytic thought processes (references)

'Hofstadter and his colleagues created a variety of computer programs that
extrapolate sequences,
apply pattern-matching strategies, make analogies, and even act "creative."
'  

For instance, he developes a 
model that solves a type of newspaper-puzzle cryptogram.

The interplay between levels of abstraction ---recognizing words in the
plaintext language, 
and reconstructing the key together from statistical and other constraints
(Ch. 4)--- is what's
similar between Hofstadter's model and what the field manual describes.

Caveats: Hofstadter's book is very dry. The Field Manual only mentions
that computers may be useful,
and gives advice that may have been useful 70 years ago.
