[gecode-users] fzn-gecode -mode gist and variable names

[Guido Tack]

The -f command line option is actually a no-op, it’s just there to maintain compatibility with the MiniZinc challenge (the specification is that you /may/ ignore the search annotation, not that you /must/…).

Cheers,
Guido

So currently the only workaround is to include all variables in some search annotation (but of course I understand that that’s not necessarily what you want to do).  I had a look at fixing this at some point, but it turned out to be more than just a few lines of code so I had to leave it for the time being.

Admittedly, the latter names are a bit awkward, but at least they enable me to relate back to the names of the MiniZinc model.  But I have no idea how to map the var[...] names to the names of the .fzn file. I have tried to edit the .fzn file in various ways to make Gist use its names, but it has not helped.  Is there some work-around?
