Comment(by josefpktd):

 anneal does not implement a constraint optimizer! Maybe the docstring
 should make this clearer.

 The bounds on the updating is just to control the locality of the
 disturbances in the annealing process.

 If you want to enhance anneal by allowing parameter constraints, you can
 attach a patch (or rewritten version) to a ticket, and/or discuss it on
 the mailing list.

 enhancements are welcome, but, as far as I know, nobody is currently
 working on anneal.
