There is also Gustavo Niemeyer's python-constraint package, which is also very preliminary. http://mail.python.org/pipermail/python-announce-list/2005-July/004153.html Laura In a message of Tue, 31 Jan 2006 10:39:13 +0100, Grégoire Dooms writes:

An other area where I've been exposed ot fixed points is concurrent constraint programming where constraint propagators are applied to a computation space until a fixed point is reached (see for instance http://www.gecode.org/ for a Open source implementation).

Does anyone know if Python bindings for the gecode library is in development? I could really use this on a project I'm working on.

I know this request is shared by several (current and potential) users of gecode. I don't have the time to develop one before summer but I am (and will be) trying to convince others to do it before. It might be easy to do by starting from the SWIG generated JAVA wrapper which is currently under development. On the other hand Logilab.fr provides a Python-only constraint programming lib based on the Mozart/Gecode idea of computation spaces and cloning. But beware it is very preliminary: the only propagator available is a generic, enumeration based, forward checking algo.
