[gecode-users] Logilab's Python Wrapper for Gecode

[Grégoire Dooms]

Dear all,

last week we have had a PyPy 
(http://codespeak.net/pypy/dist/pypy/doc/news.html) sprint about 
integrating Python and logic/constraint programming at UCL in 
Louvain-la-Neuve (view the report here: 
http://codespeak.net/pypy/extradoc/sprintinfo/louvain-la-neuve-2006/report.txt 
).

During this print we started the development of a Python wrapper for Gecode.
We were able to wrap a simple generic space which allows to dynamically 
register integer variables in it and post a few constraints. We also 
implemented a generic propgator over ints which triggers  a Python 
callback  on propagate().
The embryonic wrapper is available at 
http://codespeak.net/pypy/dist/pypy/lib/logic/gecode_wrapper/

The guys from Logilab  (http://www.logilab.org and 
http://www.logilab.fr) which had already implemented a pure Python 
constraint solver (http://www.logilab.org/projects/constraint) are in 
the process of developing the Python wrapper.

All the best,
