Call for participation

Sixth French Conference on Logic and Constraint Programming

May 26-28 1997 -- Orléans, France


The French Conference on Logic and Constraint Programming and UNIF (*), the International Workshop on Unification, are jointly organized in Orléans this year. The aim of the meeting is to review recent research work on the conference topics with a particular focus on the interactions between the different aspects of logic programming, automated deduction, constraint resolution and their application domains. JFPLC'97 follows the series of previous meetings which took place in Clermont-Ferrand (96), Dijon (95), Bordeaux (94), Nîmes (93) and Lille (92).

The technical program of the conference includes three invited conferences, the presentations of fifteen refereed papers and a poster session. A full session is devoted to industrial participants. This session is jointly organized with Orléans-Technopole and focuses on products and applications of Constraint Programming.

The official JFPLC'97 languages are French and English.

The conference registration includes the proceedings, the three lunches, the hotel Groslot reception, the visit of the castle of Blois (one of the royal Loire castles), the conference banquet on the Loire river banks.

For any further details (scientific program, hotels, access to the site, registration form, etc.) see the web pages or contact the organizing committee.

(*) The UNIF'97 workshop organized by S. Anantharaman (University of Orléans) will be held on May 28-30, 1997. For any further information, please contact unif97@lifo.univ-orleans.fr
