Ok, here a two pointers to code I found:

http://margaretmorgan.com/wesley/python/anneal.py
http://correio.cc.fc.ul.pt/~jpp/classes/heur-main/node50.html

Both provide basic working implementations. I looked some more into
the second one, so far I haven't found a bug in that SA code, but in
my wrapper:O

Probably there are more people out here using SA without the need to
publish it on the web. If anybody with a more advanced implementation,
probably even ASA or such beasts would be willing to share their code,
I'd be happy;-))
(Tim, I couldn't do a "adaptive simulated annealing" NEAR python
search -- and couldn't find an implementation of ASA or such in python
yet:-))

Me too.

It actually searches google! And that is why I was confident it was
the right thing to use metacrawler...

Probably you could write what you did, besides the "com on folks";-)
