of the art, and future developments in the field. Topics will include
modeling techniques, scenario generation, two-stage and chance
constrained models, dynamic stochastic optimization, integer and

SIGOPT provides a forum for discussing current and future developments
in a broad variety of disciplines associated with optimization, and
actively supports interdisciplinary research and applications to
industry. In particular, SIGOPT encourages students and younger
scientists to become involved in research in optimization.
A series of invited lectures sponsored by the Confrence Universitaire de Suisse
Occidentale and the Association Suisse de Recherche
Oprationnelle. This year's speakers and topics are:
- Vasek Chvatal, Rutgers University: Solving
large-scale traveling salesman problems.
- Robert Fourer, Northwestern University: Design of
Modeling Languages and Systems for Optimization.
In recent years, an increasing number of researchers, from both the
Operations Research (OR) and the Artificial Intelligence (AI)
communities, have investigated the possibility of integrating
methodologies of the two fields in order to obtain better results in
solving combinatorial optimization problems. In this context,
Constraint Programming (CP) may be proposed as a suitable environment
for performing and experimenting such integration. CP was born as a
programming paradigm exploiting AI Constraint Satisfaction techniques.
Nowadays, most industrial CP tools and systems have integrated
efficient special purpose techniques from OR for improving propagation
and overall system performance. The aim of this workshop is to enable
researchers working in the two fields to exchange ideas and
methodologies and to show that the integration of techniques from AI
and OR can lead to interesting results on real-life applications.
