[gecode-users] Python wrappers

[Christian Schulte]

Hi,

There is a direct MiniZinc to Gecode interface. However, my take on the
paper is that it is a little confusing (mildly put) in places. I am also not
sure whether that work extends beyond paper:

we're currently implementing an interface to the Numberjack Python  
library (http://4c110.ucc.ie/numberjack/home).  It's work in progress,  
but we expect enough progress for it to be usable soon.  The interface  
is generated using SWIG.

That's not so easy, because mzn2fzn is written in Mercury, and  
currently only available as a stand-alone program.  It's should be  
possible to wrap the Mercury code in a C library, but that hasn't been  
done yet.

Cheers,
