Hélène Fargier (IRIT) visiting B. O'Sullivan and N. Wilson (and also Greg Provan and T. Hadzic) at the Cork Constraint Computation Center, Ireland, from the 1st to the 10th of may.

The main topics of discussion have been :
- Approximate compilation (with G. Provan and B. O'Sullivan). In particular, discussion of Greg Provan's new results about incremental algorithms for approximate compilation.
- Configuration problems (with T. Hadzic).
- The handling of partially ordered preferences in combinatorial problems (with N. Wilson). We have in particular discussed in more details a previous preliminary work about the use of variable elimination algorithms in such problems.
