I colleague of mine forwarded to me your message concerning NNs in
Common Lisp. I have been active in the area of NNs mainly for
scheduling, but also for classification. My experience suggests that
the basic Hopfield model does not perform well, at least not when
compared with the GDS-net, our own development.
Below I give you some refs. which you might want to follow up. They
describe the architecture is, its performance measured on toy
problems such as N-queens and its application to a
demanding real-world scheduling problem (i.e. Hubble Space Telescope).
I can provide you with reprints, if necessary.

Everything is coded in Common Lisp and in principle, the code is
publicly available (though I have to check with my collaborators).
There are further papers available, concerning e.g. NNs for
classification, if you are interested. But the code was not written
in CL. Nevertheless the alorithms may be interesting to you.
